Now that verifysignatures=2 (or3) are working properly I can't use COT on my server anymore, UNLESS I make ALL the players install the mod too. My server is VANILLA and everyone joins it for NOT having to use any kind of mod ...

And if you leave your server with verifysgnatures = 0 (boy, prepare your a* ) this will be a paradise for cheaters / hackers

is there any other solution you guys are using?
