I'd just like to add that I've had to unapprove a number of Seem's uploads myself for ToS violations - a number that is quite disproportionate for just one user.
Considering the trouble Snesso has been for the same reasons (and some greater difficulties), I'd question whether it was a good idea to keep him on as Janitor, as well. Under approver:snesso order:id_asc, there's a ToS-violator right there on page 1, so it's not as if he's stopped.
