The Polk forum was beyond vile (but so is Blu-ray.com), with members allowed to take someone's name and actually add derogatory references to their sexuality or other aspects of their personality between lines to insult them in reply posts, and the mods do NOTHING. I was banned for basically being bullied there and standing up for myself (I had things said about me that were COMPLETELY untrue) and for asking questions about the compatibility of certain speakers with certain receivers.
The same thing happens on Blu-ray.com -- what a joke that place is. Their moderators are known for picking sides and having favorites during disputes. I was banned for -- get this -- IGNORING members who were ganging up on me and whom I was told to ignore, and after I did and said nothing when the insults began again, I was the one suddenly asked to leave. Post an image that they think is "suggestive" when it's not and you'll get thrown out (that's a big one there, too).
If you don't care for non-objective environments, DON'T join that forum.
