There is no stopping meme accounts and I do see 'original creators' getting upset at the lack of credit in the reposts. The most common answer is, if you care, watermark your work.
That's what makes these accounts so uniquely infuriating. They're not accidentally omitting credit out of laziness or ignorance. They do extra work to make sure the original creator gets cut out of the loop.
Maybe it would be worthwhile creating a service that did this. Although I think it is probably more like a feature of another service.
