@jerry Reply controls and ability to block direct mentions from unknowns - with safe defaults - are dev work that needs effort but if prioritised at the platforms level would be hugely helpful to help people set up new accounts that are not wide open to abuse.

Most platforms do not allow blanket access to your inbox for direct comms and notifications. Most platforms offer some level of control over who can reply.

These are fundamental and need funding and love to make it happen here.
