we've implemented a strike system similar. only difference is rather than suspension, the user group is changed to 'inmate' and the only forum they can view and post in is called 'alcatraz'
they get to decide, while in jail if they are going to return to being good. the jail sentence lasts for as long as necessary.
once it's the 3rd strike, it's gonzo time.
btw, alcatraz is viewable by all users.. they can't post in there, but they can watch the 'inmates' squirm and get admonished by the appointed 'wardens' (mods).
it makes for entertainment as well..
also, when a user is in jail, they lose Search and PM rights.
