> Maybe in isolation, although in most competitive video game spaces (which is where I've met majority of my "online friends") a disagreement between two parties tend to get resolve because it disrupts the entire dynamic.

Sure but often the most easiest way to resolve nontrivial disputes online is to remove one of the participants from the community.

> It is increasingly difficult to just "drop" someone when you friends with their IRL friends, which is also pretty common. You'll play a game and meet someone, they'll meet you and invite their friend to all queue up.

Now you're bringing in real life relationships which yes are much harder to just drop.
