Constant harassment? No because I block people at the drop of a hat. Unprompted friend request? Blocked. Playing music in global chat? Blocked. Shitty username? Blocked. Don’t deal with people, a single infraction is enough to remove internet strangers forever.

I also think I want to make a list of these accounts, I wonder if there are tools to scrape pfps and look for similar ones or any lists of them that already exist

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?

I report stuff when I come across it. I regularly get info on action being taken.

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.
