good afternoon. 

As i was wondering a bit on the umod site, checking some plugins i never heard of, i came across this and i have a small question with it. 

Is there any chance you could add an option that the plugin checks in what group the user is? that if the user is in a group that you have blacklisted, that the user gets kicked? 

reason: skin gamble sites most likely forces you to join their steam groups. With this, you could exclude these groups in some kind of blacklist by adding their group ID towards the json config file.
