and this is what I am finding odd about the many closed threads and posted warnings as of late. I do not see that they violate ANY of these rules.
I can only assume, based on what little was said, that forming an opinion that disagrees with the OP and stating it, no matter how nicely, and/or forming such an opinion partly based on knowledge from other threads, and expressing how that influences your opinion is now considered a "personal attack" which I really hope does not end up being the case long term because it squashes any serious discussion.
I have always thought "personal attack" meant things like calling someone names and the like, not disagreeing and stating why, or pointing out a pattern of behaviour, etc.
