Something dubious about this is nagging at me, and I can't stop till I've gotten it off my chest. I submit to you user #21799. He has posted twice to the blue, both times to sites with interesting content, but of questionable quality. Both domains posted (1,2) are on the same registrar, with the same basic whois info. The sum of his comments have been tepid one-liners, one to two words in length. Additionally, there is an identical post by someone with the same handle in Broadband Reports, and a complaint about similar TV-related spam in an Avengers newsgroup. Is this subtle link spam at work, or am I being paranoid?
