I decided to test and see how good multiconnect was for 1.8. In my testing, i got banned within the first minute of logging on to lunar. This might have to deal with jump/movement, because it wasnt even when I got hit, therefore it couldn't have detected anti-KB.

I am curious, whats the address of the server? I want to do some testing to help and narrow down whats causing the ban

Did not get banned within 10 minutes / some practice games. I compiled the master branch. Propably this commit is what got you banned: fd91bc8. Its not yet in the latest release. So building multiconnect yourself should fix this.
