On the topic of moderator bias

Apparently you can, at least sometimes.

Again, that depends. I have been informed that in some cases, if one reports posts too often, and is perceived by at least one mod as reporting violations only from one ideological side, then that mod at least will discount your reports as less worthy of consideration.

It has also been the case that if you do report a post, a mod will publish the fact in an apparent effort to discredit you.
