If you get a comment from a user named 'jwct123' asking for requests, block them. They have a nasty habit of commenting on any F/F fics involving smut and asking the author if they take requests for their own fandoms, without giving kudos or commenting on the fic otherwise. Their profile shows no bio, no bookmarks, no works of their own, just gifts from other authors they've managed to manipulate into writing works for them.
