Existence does not equate allowance. Have you reported their profile?

Their user name is their user ID. I assume it has been handled now? What’s your take on that after these public accusations and it supposedly being the reason to make your own spaces?

It’s a community platform. Individual, manual username change assessment and approval is infeasible. What’s your expectation?

What do you mean by harassment? You didn’t specify.
