User blog comment:Poseidon133/Why do some wikis have talk pages?/@comment-31924693-20150421212126

On the World Of Cars Drive-In Wiki, when there was no active admin to keep things under control, there was one IP user who for some reason constantly added inane comments (over 100 of them at the final count) to one page. (I suspect that he was attempting to hack in to Wikia by causing a buffer overflow error.) When we finally got admin rights (and blocked the idiot for a year), the problem then arose of how to get rid of all those comments; it proved virtually impossible, so we switched to talk pages.

Apart from being much easier to police (such rubbish as the above, if on a talk page, could have been deleted in one fell swoop), another advantage of talk pages is that they allow replies to replies.
