I dont want to decrease my accuracy, which is already down to 97%. So before reporting, I want to know the exact forum rule from the mods.
That is an awful reason to not report things! Having a higher accuracy does nothing for you. It's better to report more things and have a lower accuracy than to report less and have a higher one, the former is going to lead to more actions by mods.
Also, some things do not have set rules so it's going to be up to the mod who's looking at the report.
Do you really care that much about accuracy?
