@downwithopp This is Kell/Alek from BSO, just wanted to chime in my experiences from an outsider's (who didn't know much of all this drama that was going on) view looking in. I don't think we've RP'd with each other from other games in the past, or I just don't remember as I'm really bad at knowing who is who until it is pointed out to me.
You ran a lot of scenes and mission stuff which was great in my book, a definitely plus for the game. The minus I saw was as others have mentioned, your ability to just kill off or retire characters continuously, sometimes within months. That's a big minus because not only does it kill any relationships and connections you have with others in the past, it also leads to the consequence of other players not willing to put in an effort to build connections with your new flavor of the month character.
My advice is that you posted your apology, a good first step. Just leave it at that, there is no reason to argue with others about what happened. It might not be how you saw it, but that doesn't matter as what matters is what they felt when interacting with you. Just leave it be, go back to lurking and silent mode. Focus on changing how you behave and how you play your characters, stick with one or two characters at most and just keep them going, through thick and thin. Avoid relationships since that seems to be a trigger point, and try to shed the behavior you have identified yourself as what other people dislike and want to avoid. The only way to change for the better is to work on continuous improvement on yourself, one step at a time.
Path to redemption is available to everyone, just some roads are much more difficult than others.
