About a month ago, in the hopes of reducing forum spam, we disabled signatures for registered users. We also disabled bbcode across all publicly accessible forums.
The result was that the spam fell off a bit, and centered in the "music theory" forum.
It seems the spam comes from "forum spam companies" and that there is currently only one forum spam company targetting this site.
Given what could happen, this situation is not too bad. We have a lot of mods, and we all just check the music theory forum first thing every time we are here.
Today I am re-enabling signatures for register users. I also re-enabled bbcode in open discussion and several other forums.
Let's see how this goes. If we don't end up with new kinds of spam or new targets, we can keep these changes.
Thanks for your patience on this.
