Nice to find someone who agrees/understands.Initially, people are mad/angry/sad. But eventually, those feelings are replaced by indifference and they move on to other things.
The ones that do hang around do so because they either can't get over it, which is unhealthy as you say, or more likely are just shooting the breeze and screwing around. The same thing happens to many threads on here, when developers (either rightly or wrongly) get on peoples bad sides.
Unfortunately, it's hard for people who do still like the game / don't hate the dev to have a place in those threads. Threads that for the most part don't get moderated much if any after a certain point. So actually having more positive discussion, not getting made fun of when you post something positive and finding relevant information on a game can be very hard.
So the best you can do is to use your ignore list to manually filter out the more negative stuff. Or view it as people screwing around and fishing for likes and don't take them seriously.
I just don't see any point in all that negativity. As for moderation, the only mod here seems amongst the disgruntled themselves. Can't really keep the peace if you're part of the angry mob.
I figured I'd sprinkle some emotional maturity around. It's a genuine attempt to help them cope, really. But they're free to take it or leave it. I'm a pretty solid guy so it doesn't really bother me to get dogpiled. Even a mushroom cloud has a silver lining. I'll be alright.
