Depends on the situation. If it is round-based mode, and "X" number of players are left and each are camping (meaning the game will never finish) then the game needs at least a /shuffleteams or something to proceed.
In any other situation I'm fine with camping, but except in the extreme situations of ac_mines where 3 guys are at the top of the rock shooting at everything they see. Even though I find the mines situation irritating, I don't start kicking/banning them so I can have an easier time capturing the flags, I just try another way to get to the flag without them killing me.
Any other situation besides these are really fine by me. Of course, it is annoying when a guy above the ac_mines stairs with a shotgun is camping, but kicking them isn't the solution, going the other way and knifing them is ;)
