@Tinuviel I would genuinely love to be able to go the 'if it's just more evidence' route on this one, I really would.
Unfortunately, I have known a handful of people who are so vastly different on the game than they are in alternate channels, purely because they actively rely on the 'but it didn't happen on the game!!!' defense.
As in, I have been mid-page convo with someone, and had them shift immediately to skype to add heavy duty smack-talk to the conversation, actually stating they're doing so 'so it isn't happening on the game and they can't get in trouble for saying/doing it'. Then they flip their shit if ever it gets mentioned on game because it caused concern, trying to make me the bad guy for calling them on straight up lying about it once they're back on the MUX. Zero conscience about the lying, all the blame shift on the 'how could you ever repeat that!' ("Because you're lying and cheating, duh.")
Needless to say, while I will keep the most trivial confidences to the grave 99% of the time, I am not somebody to brag about how you cheated, harassed someone, etc. to, because I have zero respect for that behavior. I won't mention it unless it's harming someone (myself or someone else, and usually if it's just me it takes a lot to get me to give enough of a fuck to say boo), but seriously... people should not tell me this kind of thing if they want it to stay quiet. (Personal shit, no matter how embarrassing about whoever? Doesn't matter if I love them or hate them, that doesn't get relayed, period. That is just non-cool.)
These folks were an unfortunate wake-up call about it all. It's not suddenly not cheating, harassment, stalking, or abuse due to change of venue. Evidence still has to be there, but the venue from which that evidence comes ultimately makes no difference.
