Good god, MJLiverock. I suppose that story is awesome now, maybe not so much when it was happening to you. The style of UW-Madison housing violations that can get you into University (not just housing) suspension-ville are fairly major: assault, theft, selling prohibited substances, stuff like that. If something like that has happened, it'll probably turn up if he does reapply because my employer does background checks for every hire (including re-hires). Then again, if he is able to reapply, it'll be because his appeal was successful. Ehh, it'll become clearer soon enough.
