Limiting Reports / Show A Post Was Reported

[OhSoRy]

Hi everyone. Hope you're staying safe during the pandemic. I was wondering about the following:

1. Limiting the amount of times a post can be reported. If a member goes to report a post that someone else reported, maybe they can see an "Already Reported" message.
2. If a post was reported and warned, the member can see that a warning was issued.

Are there any plugins that can do this or maybe a code tweak I can do on my own that would allow this to happen?

Thanks.
