Why not? Why force them upon us? Why not let us choose to always reject them, and if a user has chosen that, just show the sender an error?

I agree, it should be possible!

edit: @supertestnet

you must have a problem with your receive wallet. i zapped your comment with sats but CCs were sent. There are no errors in the logs.

I want the sender to be unable to send them to me.
