Just noticed this with this helpful notation. Pre-translation check validates that there's content but post-translation nulls it out before loading. I'd expect other cases lurk as well -- the above with [img], but maybe [span], etc...

Huh, yeah, that too: tags surrounding nothing qualify as okay.

I mean, I suppose it's one better than ".". Maybe its a feature!

I don't get it. There are an infinite number of ways to post a blank comment, even without resorting to using banned tags, e.g. <b></b>. There is no realistic way for the parser to be able to detect a truly blank comment, without having to parse an arbitrarily complex nesting of tags. It doesn't seem very worthwhile to worry about this.

Rhomboid, if you have no content that is not a tag it is blank? Is there some tricky way to generate content from html tags?
posted by BrotherCaine at 3:29 AM on April 17, 2007


I don't understand what you're asking. The current comment/post parser only knows to reject a comment/post if it's actually blank, i.e. contains no characters (or no characters other than newlines.) But you can also write comments/posts that contain characters but nothing to display, and the task of writing a comment/post parser that can detect this in all its forms is very, very hard. It would have to be a full HTML parser, since you can nest HTML tags to an arbitrary depth. When you combine this with the dozens of Unicode entites for nonbreaking spaces or hair-spaces, it becomes even trickier. In other words, it's not possible in a reasonable amount of effort to be able to reject all posts/comments that display nothing, so it's not worth wasting mathowie's time trying in vein to do it.

My arbitrarily complex nesting of tags is broken. It's only blank half the time. Hope ples?

If you're complaining about images appearing in previews and disappearing in your posts, most of us got that memo half a year ago. If you're complaining about empty tags causing empty posts, that would be the fault of the user writing a post consisting of empty tags and not noticing the preview field's blank.

It might* not be too hard or problematic to throw a more robust check for post-filter blankness into the posting scheme. Agreed, Rhomboid—doing it Right would be a tremendous pain. But doing a post-filter match for anything other than some common whitespace characters would at least help.

Is there some tricky way to generate content from html tags?

Not especially tricky, but tags like <img> and <hr> represent content but are not text. I can't think of any examples of this, however, that are still allowed around here anymore, so why wouldn't kirkaracha's method work?

No Dave, she means the thread mention didn't make it into the podcast. It was a blank bugs thread from six years ago, and she randomly found it and we talked about how it might go off today (many more blank comments), but I didn't want to encourage people screwing around with mefi trying to display nothing, so I didn't leave it in the final version of the podcast (which was already 40min long anyway).

Did we learn NOTHING from the Legend of John Henry’s Hammer? You can’t replace people with machines! Johnny Cash would have the following to say about this…

The Legend Of Matthowie’s BanHammer
(Live at Folsom)


Matthowie's pappy woke him up one midnight
He said, "'Fore the spamers comes an get me- I wanna tell you- listen boy!
Said, Learn to Host a Site, learn Moderate all Night, learn to post and comment too,
And take my BanHammer! It'll do anything you tell it to.

Matthowie's site had about a dozen spamers,
Matthowie had to ban each about dozen times
But when the site got full and the servers need money,
He said, how bout ya pay me five dollars at a time, startin tomorrow,
To pay for the servers on this site of mine.

Some nasty trolls they shouted, Hey - BanHammer swinger!
I see you got your own website boy, but what else can you and that hammer do?
And he said, I can Host a Site, I can Moderate all Night, I can post and comment too
(can ya swing that hammer?)
It can ban anyone i wants it to.

Well Matthowie BanHammered on the server.
He'd give a grunt and he'd give a groan with every swing.
Fanboy's for miles around heard him bannin and logged on,
To watch him clean up them threads they seen. Lord what a swinger!
Just to watch him fix up their computer screens!

But them bad spamers come up laughin' at Matthowie.
Said, You full of AJAX now, but you about through!
We gotta brandknew SpampBot gonna shit all on yer website,
Then what's yer banhammer gonna do? Huh, Matthowie?
This viscious scripting surely gonna pwn you.

Matthowie said, I got about 50000 users,
And havn’t yet bought them all their ponies.
Did the lord say that machines aughtta take the place of living?
Can your spambot overthink a plate of beans? (amirite)
Naw they can't see the people though the data streams

Matthowie said to teh Spamers, A man ain't nothin' but a man.
But if you'll bring that SpamBot round, I'll beat it fair and honest.
I'll die with my BanHammer in my hand but, I'll be laughing
'Cuz you can't replace this metafiltern man.

There was a big crowd of people at the Weblog,
Matthowie said to the SpamBot, How is you?
Pardon me mister SpamBot, I suppose you didn't hear me. I said how is you
Well can you Host a Site, can ya Moderate all Night, can ya post and comment too?
Listen - this moderator's talkin' to you!

50000 users hollered, Go, Matthowie!
Then somebody hollered, The Server's's caving in!
Matthowie he told cortex, tell the kind folks don't worry.
That ain't nothin' but my BanHammer suckin' wind! (It keeps me typin.)
My leet skills in deletion I protend.

Cortex, told the people, move back further!
I'm on the gray and there ain't no spambot to be seen.
Bounced off the blue and green, but yet ain't got the brains to quit it!
When she blows up she'll scatter cross the web! (Lord Lordy!)
When she blows up she'll scatter cross the web!

Well Matthowie had a honest admin,
I believe the lady's name was Jessamyn. (Yeah she was the backup admin.)
Matthowie threw his BanHammer over his shoulder and went on home.
And early next mornin', he said,
Come here Jessamyn Come here
Ya know, I believe this is the first time I ever watched the sun come up
That I couldn't come up with it.
Take my BanHammer, Jessamyn, and get back on the Weblogs.
And when you're swinging at them trolls,
But, but tell them ain't all you can do.
Tell 'em I can Host a Site, I can Moderate all Night,
I can post and comment too (Ain't no machine can!)
That's been proved to you!

There was a big mess of comments in the obit thread.
And no one even tried to flame or snark.
Traffic goes go by on the website Matthowie made.
Some of 'em say, 'Mornin', webmaster! You shor' was a BanHammer swinger!
Then they go on by, pickin' up a little speed. (Clickity clack, clickity clack, clickity clack, clickity clack)
Yonder lies Teh Metafilterman, oh lord!
Yonder lies Teh Metafilterman.
Yonder lies Teh Metafilterman, oh lord!
Yonder lies Teh Metafilterman.
Yonder lies Teh Metafilterman, oh lord!
Yonder lies Teh Metafilterman.

The Sumerian Ban

Out on the road for forty days,
Last night in Lagash, put me in a haze.
Sweet, sweet Ishtar was doin' her act,
She had the whole show and that's a natural fact.

Up all night with Enkidu:
I got to tell you, I'm in his crew.
The skies roared with thunder, then a stillness like death,
The Sumerian Ban hit Gilgamesh!

It's the Sumerian Ban
It's the Sumerian Ban
We're comin' to your town
We'll raze it to the ground—
It's the Sumerian Ban!

Four young Elamites in Susa town
Waitin' for the Sumerian Ban to come down,
A feelin' bad, feelin' tight and it's time to smite
Sargon of Akkad, he was outta sight.

Now these fine fellows, they had a plan,
They was out to foil the Sumerian Ban.
They said, "Come on dudes, let's get it on!"
But we proceeded to tear Susa down.

It's the Sumerian Ban
It's the Sumerian Ban
We're comin' to your town
We'll raze it to the ground—
It's the Sumerian Ban!
