unlockable trading cards, given about 1 or 2 a day, extra card drops can be rewarded for frequent posts that don't get excessive negative votes, and users can get punished, every time they have a reported post they lose days until card drops, the cards are all pepe.
maybe every 100 or so positive upvotes we get, either in comments, posts etc, we get extra card drops in the following few days, and for every so many votes we do it will give us a new card.
ergo we can literally collect pepes, and trade them as fit. badges can be rewarded based on percent completion on pepe series.
