Of course they should be banned for intimidating staff and their own fans, of course they should be banned for ripping down air con units. The fact of the matter is they aren't going to stop being arseholes, this isn't going to stop, and it's not a problem that only Sheffield United fans encounter.
There's one of these threads on here after every profile away game so I can only assume the club are aware of what goes on. If the club were going to act on their behaviour they could have done it at any point on the last few seasons.
