A group of us were at Elektro the other night and ran across a guy next to the police station replicating himself over and over. This indeed caused massive lag/desync and he did threaten to crash the server if we continued to kill his clones.
I believe you're aware of this issue but I wanted to point out that some of the server crashes/hangs could be attributed to this kind of thing.

He did eventually logoff and the server went back to normal. I am hoping that you will turn on the Active BE soon to combat this kind of thing.
