Well it all depends on the program you are using. They ban your IP (they have me) if you keep trying to reconnect once they terminate your connection. They usually terminate your connection once the time has expired, but that is not always the case for some reason...

Regarding the non-CIS being a problem: dude, I am 100% sure "ex-Russians" in the U.S./Europe have been using this site alot more than any CIS country. This reduces sites to a crawl, but allowing them in the middle of the night, when the CIS traffic is the least, makes more sense.
