Is there anything you can do against spam answers?
Over the last week or so the amount of spam answers on Ask Ubuntu has significantly increased (a couple of deleted spam answers: Reinstall of OS after CPU Upgrade needed?).
Right now I edit the answer to remove its content, flag it as spam, and sooner or later they get burned alongside their users. Some questions seem to attract such answers, which can be protected, but that's all we can do.
This is a - likely incomplete - list of the URLs with the first batch showing up multiple times (could be true for the rest, I just went through my spam flags and I'm asleep during the spam peak time):
