Hi,
Spam started to appear in the ET bug tracker, so we installed a spam-filter plugin. We didn't take the time to configure it in a nice way yet, and it doesn't support captchas as it is now. Please let us know if you have problems because of this. The last thing we want is people not using it because of a lot of false positives.
thanks, Frank Loeffler
