like, for all the times I get utterly pissed off at Eugen, I can kinda see where he's coming from. You don't want to have anyone have a bad time on your server if you can help it, and if you're already inclined to dislike people on other servers it's really easy to believe that it's a pit of vipers nobody ever needs to deal with and block the whole thing.
But you can't really think like that unless it *is* a huge pit of vipers, and in my experience there have been very few places that are just completely irredeemable to the point where you have to precommit to ban everyone in an instance block.
You can suspend individual remote accounts as an admin, and I encourage you to do that if you and others on your server feel that is the best thing to do.
