On a website that has no message system, how can I report a troll who keeps bullying me?

@DiegoWolfe I haven't found a report feature that enables us to report members, only postings. I want that member to be warned to either leave me alone or get the hell off the site.

@Crazychick cant you block him

@1olderguy20 It's not a him, it's a her (unless it's that stalker disguised as a woman). I could have sworn I said that yesterday. Now, how can I block her when there isn't a block feature on that site? 🤔
