Another good way of slowing down these forum spammers is, if applicable to your forum, disable registration from certain countries. Blocking all of Asia, Brazil, Russia and several other countries where spam is likely to originate cut down the amount of spam and fake profiles we get by a lot.

You don't need to be a pro to recognize fake profiles, you just need to know your forum membership.
