I really don't understand how people say things like that... take away sploit, antd, splice and there goes half the swarm speeds (no jokes intended). Members are not entirely disposable, you know. Most members on SCC actually use shared boxes instead of dedicated ones, with very few exceptions, such as the prominent names above.
EDIT: I guess what I'm saying is, it depends on who they're giving up. I'm sure SCC would have a lot of regrets if they let the server randomly pick 100 members and throw them out, which is exactly what trackers do when they ban countries. Fortunately SCC only bans new sign-ups, from said countries and weeds out the rest of the problems. Flat-out saying that any/all members are disposable because there will be more to replace them is wrong.
