* 1) connect burst is happening, and for some reason a legit |
| 157 |
* op has sent a KICK, but the SJOIN hasn't happened yet or |
| 158 |
* been seen. (who knows.. due to lag...) |
| 159 |
* |
| 160 |
* 2) The channel is desynced. That can STILL happen with TS |
| 161 |
* |
| 162 |
* Now, the old code roger wrote, would allow the KICK to |
| 163 |
* go through. Thats quite legit, but lets weird things like |
| 164 |
* KICKS by users who appear not to be chanopped happen, |
| 165 |
* or even neater, they appear not to be on the channel. |
| 166 |
* This fits every definition of a desync, doesn't it? ;-) |
| 167 |
* So I will allow the KICK, otherwise, things are MUCH worse. |
| 168 |
* But I will warn it as a possible desync. |
