133 * 2) The channel is desynced. That can STILL happen with TS
135 * Now, the old code roger wrote, would allow the KICK to
136 * go through. Thats quite legit, but lets weird things like
137 * KICKS by users who appear not to be chanopped happen,
138 * or even neater, they appear not to be on the channel.
139 * This fits every definition of a desync, doesn't it? ;-)

193 * - Personally, flame and I believe that server kicks shouldn't
