It absolutely is not a load of rubbish. I have personally observed it many times. And I have spent a LOT of time observing. I don't claim to have "proof" however I know what I have seen. I also didn't say "reputable" (a strange word in this context). Also, every/most Casino does not engage in this but some do.
Your claim "they wouldn't do this because they already have an edge" is just silly. Why wouldn't they take a chance to make more money? Especially since, as you say, "proof" is a bit hard. An accidental bump. That's all. No intentional cheating here.
I would like to re-iterate my main point. This is something to watch for if you are a roulette player. If the table wobbles when you push against it... walk away.
