143 * 2) The channel is desynced. That can STILL happen with TS
145 * Now, the old code roger wrote, would allow the KICK to
146 * go through. Thats quite legit, but lets weird things like
147 * KICKS by users who appear not to be chanopped happen,
148 * or even neater, they appear not to be on the channel.
149 * This fits every definition of a desync, doesn't it? ;-)
150 * So I will allow the KICK, otherwise, things are MUCH worse.
151 * But I will warn it as a possible desync.

201 * the kick should show up as coming from the server which did
203 * - Personally, flame and I believe that server kicks shouldn't
204 * be sent anyways. Just waiting for some oper to abuse it...
