looking for an anti spam solution without external content

[X-or]

on vb 3 we had this great and totally efficient mod

but on vb 4 I'm only seeing mods relying on external content which can be potentially more malicious than spamers themselves

can you please recommend me any anti spam mod that does not rely on any external content?
