122 * 1) connect burst is happening, and for some reason a legit
123 * op has sent a KICK, but the SJOIN hasn't happened yet or
124 * been seen. (who knows.. due to lag...)
126 * 2) The channel is desynced. That can STILL happen with TS
128 * Now, the old code roger wrote, would allow the KICK to
129 * go through. Thats quite legit, but lets weird things like
130 * KICKS by users who appear not to be chanopped happen,
131 * or even neater, they appear not to be on the channel.
132 * This fits every definition of a desync, doesn't it? ;-)
133 * So I will allow the KICK, otherwise, things are MUCH worse.
134 * But I will warn it as a possible desync.
