Was playing on a server this evening and some guy called "97 Seal" was repeatedly crashing into me, following me round the track and knocking me off, so i just carried on riding and ignored it.
I went on the Dedicated server with Hurren midnight SX on it, within 2 minutes he started to a poll to eject me and now im banned...
That's sad, but you're only banned from that specific server until it restarts.
There's lots of little dickheads out there that will vote you out, wreck you or just randomly mess with you for entertainment. Also, some just want their friends only. I've been kicked for no reason too. That's the nature of online gaming.
