Every day I get at least 5, and I just hit the button to block them and report as spam. I don’t want to reply to the messages since that will probably only make it worse. Is there somewhere I can register the number that’ll spam them back or something?
Edit: legal suggestions only, please


Definitely don’t reply. I don’t think the mark as spam does anything for SMS. You can report to FTC but they probably have a huge bank of numbers so doesn’t make a huge difference.

Maybe you can set up an automation on your phone to automatically block or delete messages with certain criteria (e.g. keywords, number status/unknown)
