Lots of Xrumer spam popping up on here lately...

Pretty typical Xrumer Q&A post. Usually with these the program will register two accounts, one asks a question like "where can I find x" and the second account will come by later to help answer the question by posting a link to the spammer's site about x.
EDIT: Nevermind, on further inspection it looks like this probably isn't a Q&A, the question was scraped off of Yahoo Answers. They'll probably just end up adding links in the profile/signature and never post again.

These two are actually kind of interesting. The bot is pulling content from posts in the topics it's replying to, jumbling it up and changing some words via a thesaurus database to where it
almost looks like a genuine comment from someone that isn't very fluent in English. The stuff that the emilysoft account is posting is pretty obvious computer generated junk, but luluxiu's posts are pretty crafty.
