Now I have enabled a simple spam protection to make it bots harder to add comments to my blogs. The reason is in the last week the amount of spam dramatically increased and it was not possible anymore to handle this problem with a blacklist of common spam content.
I don’t like complicated computer generated pictures which are so difficult to read that even humans will become problems to decipher them. That why I am using a WordPress Plugin called Math Comment Spam Protection Plugin from Michael Wöhrer. The user has to solve a simple math equation which is easy enough that nobody should need a calculator for it. For bots it is hopefully a big obstacle to solve 4+2.
So far it works pretty well and no unwelcome comment found its way to the moderator queue or even the frontpage.
