It is easy to recognize this as a fake, because there is no such thing as a prime minister in Nigeria :lol:

I'm afraid Bayesian would add more work (dealing with false positives mostly)

Quite a bit of the spam is in rusky. Could we not put a block on none latin text ?

Perhaps; it could always be pre-trained on the current message corpus first though.

Also, we are mostly talking about first posts by fresh users I assume? Most often starting a new topic for that message as well?

How many in a day/week are we talking about? Could the "report this message" button be smartened up with logic to nuke fresh accounts when some set of reliable/established members report a message?
