No, but like it or not the USD isn't known for those things. It's known for fueling the global economy, being the medium of exchange for literally every good and service known to man.
Actually on the black market the US is known for money laundering, funding terrorism, and lots of other illegal activity. The black market is cash based after all.
You should only be able to dislike each post once. Likes can already be manipulated with multiple likes.
Disliking is a stupid feature which destroys harmony. Use instagram and realize how positive it is because it has no way to dislike. Multiple likes are actually a realistic feature.
Gotta be careful because we don't want a reddit system where sock accounts can easily get posts hidden from view. The best social media is the place where good ideas are allowed to propagate virally.
