I guess these settings (to be applied in mod_muc) should have an effect
on joining/leaving a MUC, too:

* min_message_interval defines the minimum time allowed between two
messages. This option can be use to limit the flood on the MUC service.
If a user sends messages more quickly they are rejected with the error
"not acceptable".
* min_presence_interval defines the minimum time allowed between
presence changes. Presence are cached before being broadcasted and after
the interval duration, the actual presence is send to the room. This
should limit presence flood coming from a given user.

Defaults are 0.4 and 4.
