More goes on behind the scenes here at PC than most members see. Problems with a member, or two, have been going on for weeks.
If all you know of is the one big incident, than the system at PC worked. Part of the guidelines is to make all things supportive: posts, PMs, chat. If there is a problem, copy the chat, notify a mod of the post etc... and make your complaints privately to the mods..not out in the open in the forums (as most websites do.) It's done that way to try and work with the troubled members, and to keep the whole site from giant ebbs and flows. (The site will still ebb and flow, but within a more acceptable range

)
Please don't feel like if you make a mistake that you'll be banned. We all make mistakes. It's the constant, consistent, and alas also the complete breach of guidelines that have resulted in the measures taken this week, imo.
PC is here for you, just like always. It's a good place to be.
