Hello! My first time here.
Want to ask for assistance in a problem with fake users removal.
Some time ago my Wiki was attacked and as part of the attack a list of fake usernames was created.
Now I am trying to remove all these fake entries, but using the delete button doesn't work, returning error. I assume this is due to special characters, like : and ?, in the fake user names.
I attach a screenshot here.

Will appreciate getting an advice of how to solve this problem.
