I don't know, I always feel like there has to be some reward to incentivize people, even if it's dead simple.

Like, you can choose to have your name publicly displayed on a thank you page (this would work well with BMAC, since donations can be both anonymous and not), or have your username be of different colour or have some badge next to it.

But then again, I don't know how I would fit that into this meme page, and I'm definitely not an expert having earned a total of two euros of donations (yet to implement some reward system).
