A fix could be to modify the "delete user listener" to look on subwikis if the deleted user is a member of a group of these subwikis.
It can have a serious impact on performances if there is a lot of subwikis and a lot of groups, but it's quite easy to implement.
Any other idea?
Another idea would be a scheduler job to regularly clean up users in subwiki groups. Of course it's a workaround, the best would be to have a DB design that allows to quickly remove a user from all subwikis in one go.
