Tumblr curse 

A term for the seemingly ubiquitous trend on Tumblr where character’s skin colors tend to be drawn with noticeably different physical characteristics, like being more fat or dark-skinned, than they actually are in canon by Tumblr artists. The reason for this is unknown, but the most common hypothesis is that the artists on Tumblr subconsciously make the characters look more like themselves, such as being overweight, of being the main cause behind this phenomenon. Some of the more famous examples of this trend being franchises that are very popular with Tumblr users like Steven Universe and Harry Potter, due to their character’s being very fast and loose with physical description, making it very easy for Tumblr artists to insert their own ideas of what characters look like, even though Tumblr artists often ignore the very few distinctive physical characteristics given to them in canon.

Alice: Hey Bob, why did this artist make Ronald Weasley really overweight in this fanart, despite him being described as “tall, thin, and gangling” in the book?
Bob: Must be the Tumblr curse.
