Looks like the limbs video has now been taken down!Watching the limbs video I think I see what might be the problem here. I’m sure if you’re holding a drink and you celebrate then the contents might spill, probably will, and that is likely to get yourself and those within touching distance. Getting banned for that would be way too harsh.
However, that video clearly shows cups travelling 20-30 rows down, that isn’t a ‘we scored - hooray - whoops’ moment. That is deliberate and probably premeditated. That does need to be dealt with.
