If the network you are on uses epona services you may find what you ned under /cs help akick
You can specify a mask there which will be autokicked if the mask matches with the users mask.
The mask by itself has following structure:
unencrypted
aaa.bbb.ccc.ddd / 127.0.0.1
encrypted
ddd.ccc.bbb.aaa / 1.0.0.127 / 11de379d.26d9672f.26d9672f.lkme92as
If the user has any reverse record it will be in the mask too:
localhost.net / 1.0.0.127 / 11de379d.26d9672f.localhost.net
This means that it is the best to ban *.ccc.bbb.aaa or by ident. Be creative !
