This weekend a massive spam bot attack came about. I wasn't aware of this until today, but luckily the moderators and Aquila took care of the worst. Massive thanks to them!
I've taken some measures to avoid this in the near future:
I've made Aquila administrator, so he won't have to create an emergency admin user again.
I've set up new registrations to be activated by myself, so all new registrations go through the music-playground@music-playground.net mail for now. This will eventually be changed to email activation, when things cool down.
New users needs to post 2 times, before they can create a topic.
A captcha is set up instead of a Q&A security question.
This will help keeping an eye on spam bots for now.
