Yea, try coming back in the next time you're gaming, even if it's empty just to see if you can get on.. We're pretty good about giving warning prior to kicking/banning.. You'd have seen something in all chat, or from a private message via the rcon tool (which also appears in the same place as the chat in game), generally at least twice unless you were above and beyond the call of rudeness, which - If you're posting here I doubt ya were..
The game automatically 'temp bans' you for excessive TK's, or too many within a certain time period. These numbers, as well as the 'somewhat' random temp ban time are complelety out of our control, as well as any other ranked server, and are hardcoded (well, not really, but they don't allow us access to them) into all ranked servers.. We have observed the following in regard to temp bans: They last a maximum of 20 minutes, and/or there is a high probability that after a new map loads, the temp bans will be cleared.
Please do repost here and let me know if you were able to get on though, and hopefully we'll run across ya in-game
If you have problems, I'll PM you personally and figure out what happened, but from memory, your name doesn't seem familiar to me at all (good thing), so I think it was probably just a temp ban issued.
