Recently the number and different ways of spam attacks on our community forum has increased dramatically to the average of around one successful spam account per day. For comparison, genuine registrations happen more on a monthly basis.

I’m not going to tolerate this and will defend the forum against spam. Therefore I had to turn off guest posting and immediate access after registration. Instead, I will unlock every registration attempt manually after writing a short welcome mail and analysing the answer (anti spam Turing test).

I will also do some research into more technical ways of fighting spam but for the time being this seems to be the most promising strategy.
