What do you call to those people whose judgment to other people are bouncing back to themselves?

I think you mean that the person id a hypocrite which is when one person says someone is dumb when they are just as dumb as them I hope this answered your question. To your optional question I think that they can can say what they want but its its not appropriate or horrible then report it if its not then im afraid there is not a lot you can do
hope this helped x
