Disagreements and civil arguments are perfectly fine. However, outright hateful, hurtful, and/or libelous comments directed at other board members, or people affiliated with the bands will not be tolerated. You are free to criticize, just do so intelligently and responsibly.
These simple guidelines are here so members can feel free to contribute without being unwittingly attacked simply for having an unpopular or different opinion than the majority. We’re not out to censor anyone. No one is keeping you from sharing your opinion with the world, but as the ones who put forth the countless hours of work on this website, we have the right to have a say what goes on in our house.
