Could it be possible to visually indicate if you yourself have liked/reported/... a post?
At this point it is a gamble whether pressing like will increase it or not since you can't see if you already did
I also made a similar post about this, but based on thumb positioning when left Handed scrolling.
Having a visual indicator of one's post actions prevents users from making actions that they are unaware of and reassures them that they made and action they intended to make.
We could just treat the community like instagram and post lots of shots of our combined gluteus maximus. I kind of doubt that helps the forum though.
