Reporting My Content?

I'm wondering if I get my comment to 'stick' which is basically undercover advertising.... if it's there over a certain period of time....

Basically does it work like upvotes.... upvotes are worthless after some time (they dont work).

Does reporting work the same way (don't get [removed] after a certain period of time)?

Old posts aren’t automatically safe, a late report can still remove them.
