This time two unregistered accounts with successive user numbers are the ones. One posts a question while the others posts seconds later with the spam answer solicited by the off-topic question. Deleting their accounts isn't stopping the spam. I flagged but I think everyone should be on alert for this attacks.
2Am guessing this are FUD users from Microsoft trying to create chaos before the awesome power of 13.04 comes out. Anyway, users gone now.– Luis AlvaradoApr 24, 2013 at 3:29
Spammers are attacking every website. That's what spammers do; they spam.
Just flag the posts you find. If enough people flag the system will take care of things automagically. Otherwise a moderator will nuke the post when we see your flag.
We don't need a Meta post about every instance :p
