wtf with the spamm?

[Trokinos]

The problem with banning IP ranges is that you'll ban plenty of innocent people along the very few spambots, and spambots that use "dynamic" IP (or "manual" spam makers, as not only bots are spamming but there are people paid for that too) wouldn't be affected at all.

But the other solutions proposed work, many other discussion boards are using them and it makes spambots much easier to deal with for the people administrating those boards.
