Yes, you certainly have a right to protest. On every PM in the upper right hand corner there is now a REPORT button. If you get a PM from a mod that you think is out of line and/or you think you're being unfairly targeted then you should report that too. All the mods will see it. The discussions this generates in the back room will improve our performance.
It's not unthinkable that a mod get's so fed up with someone that their behaviour starts to become a problem.

This would be great, if all the occurences happened via PM. However, the point being made is that there is often no notification of an action being taken. Sometimes it's obvious what the action is and why, but often times not.
