Something I noticed about the funserv services:

Giving a funserv bot @ in a chan gives a channel exemption from the "no users so botserv leaves" rule
Without any op's in the chan after 15 days the channel drops.
I found a way to keep it open indefinitely.

The loophole:
1) register a channel
2) add a botserv bot
3) add a funserv bot [stats, etc.]
4) give the funserv bot @ ['pseudo op']
5) set modes "+l 3" and "+k password" [keeps everyone but you out]

A good example of this is a chan I tested it on: #frozen [key = frozen]

This could cause problems, users could 'filibuster' channels from being used/dropped this way
