FR's keyword search, is my guess. That same function which provides useful references also points the way for those who aim to disparage.
Actually, of those anti-Apple FReepers who regularly post negative comments on Apple threads, I find Dennis to be one of the least bothersome overall. His comments are generally so wildly over-the-top silly that they're easy to spot and skip; and I sense that he actually has a sense of humor (albeit warped) with regard to his eternal enterprise of bedeviling Swordmaker.
While there certainly are a few truly hateful anti-Apple folks who maliciously mar the Apple threads, I view Dennis as the court jester of that regime. And anyway, I'd much rather poke sarcastic fun back at someone like Dennis who will good-naturedly return that humorous fire, than get caught up in a flamewar with someone who comes off deadly serious.
I mean, it's just an internet forum. Everybody can afford to lighten up at times.
