Hello, i've been through many minecraft checkers and I seem to have a problem. I'm using checkmate and while checking a 470 long list, it stops at 45 working accounts. Until recently I thought it was actually only 45 working alts. But I soon realised that somehow the minecraft servers are blocking me to check alts. I'm using a proxie list of 1500 proxies.

I tried to log on to my own account and it didn't work, this is when I found out my ip was blocked. It works again after 5 minutes though. I really want to get through the 470 without any interruptions because I don't know where i'm at the point it gets blocked.
