User blog comment:Skyzod324/KiteSexual is vandalizing pages/@comment-5780397-20150902091712/@comment-4783583-20150903190153

@pedronorris if somebody makes one edit on one page anyone can undo it but if some makes mutliple edits on one page only those with the right, right can roll those edits back. however when somebody edits in between then only part can be rolled back, in this case after I blocked kitesexual he came back with a new account and continued his vandalizing and since he had done three edits as kitesaxual and one edit as icantremembermyoldusername I could only undo icantremembermyoldusername's edit and not those he made a kitesexual and since he as kite sexual removed half of leorio's page I had to remade that half manually which took a lot of time.

Also this is not a real life classroom where a teacher can make a student do line, the best we can do is ban people we cannot comply them to fix the stuff they wrecked, nor would we trust them too.
