@kkarhan I am not aware that Mastodon has integrated functionality to stop reports, does it?
If a local user were to abuse the report function, we would talk to them or kick them. If a user on a remote instance were to abuse the report function, we would talk to their administrators, and if they declined to take action, we would consider stopping federating with the instance.
In any case, I think adding that requirement to a spam manager is not the right place.
