I'm going to go ahead and get ahead of the curve here and say this topic is about open and clean discussion about ThemeParkReview.
That said I'll start. On multiple occasions I have witnessed many members of youtube be blocked for posting argumentative thoughts that were in no way personal attacks but taken as such. I have seen former members of TPR come here after being banned for posting an unpopular opinion then getting flamed out in the forums before getting banned with a direct message stating that they are no longer welcome.
Sure these are horror stories but they have happened. The main reason people dislike TPR is because it appears to be a dictatorship in the sense that anyone who disagrees is a lesser human being. I have not been mistreated personally but that's simply because TPR isn't my cup of tea and I don't post there. However from everything I have witnessed happen to friends, colleagues, and acquaintances it appears to be a pattern of disrespect towards members.
EDIT: I'm so sorry, Welcome to CoasterCrazy! We are happy to have you
Truthfully I'm happy someone posted about this. I think it's fair that we encourage open discussion on this topic.
