To give members the benefit of the doubt and try to turn over a new leaf. We don't auto-ban (unless the problematic member grossly violates a site rule), we PM all involved parties to hear all sides of the story, and we give many chances. I daresay there have been times for everyone when a second or third chance benefited their situation, no matter the situation, right? I think Admin kind of sums it up here, in one of the previous posts he made:
I can assure you that the intent isn't to remain hovering over anyone who enters chat with our fingers ready to click and remove their access at the slightest hint of a broken rule. I think the Guides and I all understand what online life is like. We know there are trolls... We know there are annoying people... We also know that there are people with nothing but the best intentions who sometimes make mistakes. If anything, I have worked really hard to give people the benefit of second (and sometimes 3rd and 4th) chances because I know what it is like. I think we try to be fair. Now the downside to all this fair ness and chances are people who say 'whatever' and try to wreak havoc anyway. This gives us a tool to block them out.
Now, I am still unsure as to why these people aren't being reported. What's the harm in reporting problematic members again and again? That's why the report function is there. If anything, this brings them to our attention so that we can take the appropriate action in a timely manner. If no one reports problematic members, how would we know what issues to deal with? You may think that we can just refer to the backlogs and sift out problematic members eventually, but honestly? Admins and Guides would be here forevermore trying to complete that daunting task. We do our best to remember repeat offenders. We may have an approval system in place but even before the approval system came to be, we also counted on other members (especially those who frequent the chat room) to be our eyes and ears, especially since Admins and Guides can't be around 24/7. There's even a section in the User Guide on how to report members in Chat.
So on the one hand, members are aggravated because there are spammers and trolls in the chat room (and sometimes, they don't do anything about it) and on the other hand, they become aggravated that there's now a new system in place to try and have more control over who gets in. This puts us in a bit of a bind. I'd like to remind everyone that the original issue was whether or not we should close down Chat outright. The approval system is supposed to be an alternative to that. All this didn't stem from nothing because there were more than just "a few" members having problems with Chat.
