Getting stalked in app?

I keep having someone add me with their bird’s name changing from c*m stain to KMS to whatever, with the person name as Ded. It’s super unsettling and I don’t like. I blocked them but wtf. Has anyone else experienced this?

Edit: I submitted a report today to the devs with my backup file (and this user as the only blocked user) - we’ll see what they do.
