If you do something other than idle, like part, quit, talk in the channel, change your nick, or notice the channel, you are penalized. The penalties are time, in seconds, added to your next time to level and are based on your character level. The formulae are as follows:

Nick change 30*(1.14^(YOUR_LEVEL))
Part 200*(1.14^(YOUR_LEVEL))
Quit 20*(1.14^(YOUR_LEVEL))
Being Kicked 250*(1.14^(YOUR_LEVEL))
Channel privmsg [message_length]*(1.14^(YOUR_LEVEL))
Channel notice [message_length]*(1.14^(YOUR_LEVEL))

So, a level 25 character changing their nick would be penalized 30*(1.14^25)=793 seconds towards their next level.

Penalty shorthand is p[num]. So, a nick change is a p30 event, parting the channel is a p200 event, and quitting IRC is a p20 event. Messages and notices are p[length of message in characters].
