Not all people handle things right and the fallout can happen to the wrong people.
Back when i and my big brother played minecraft on a private server the mods were totally ignoring the personal insults one person was slinging towards my big brother and retaliate when called out on it.
In a smaller avatar site that was made by two people as a school project there was one person that was constantly harrassing me and when i told the mod they banned me for a week since the offender was that persons friend, never got back to that place.
Back in the day when i was on WoW, i joined a guild managed by a couple and the one shit-talked the other to the whole guild whenever he wasn't on. Then someone (me) recorded the shit-talk and passed it on and the next day the guild was gone and they had broken up. Not sure if that is a good result or bad but i did feel that insulting people behind their backs day in and day out wasn't right.
These aren't really familiar to what you posted but the internet isn't always a place where opinions go trough and are listened to?
I am confusing myself the more i write.
