Regarding the Sombrella's situation (there's none). I've seen some shitty behaviors that I wanted to share.
Harassment, sub-tweets and shameless promotion of 'edits'.
You know Paint isn't a good software right ? Oh that's right, you need Paint to make your blackface edits

Btw this is what I meant by harassment ; QRT all Sombrella's arts with a tasteless comment.
Also dating someone at 17 yo is gross ? Did you know that, in some relationships, people have sex as minors and/or before marriage ?

And if it was only one person... nope ! They're all promoting themselves over someone who didn't do anything wrong.
First is Paint + Blackface again :/
Second is just someone who duplicated Ruby's original hair and let a white line on the right side :x

Conclusion: Jealousy isn't sexy, jealousy doesn't make you original, jealousy is just ugly and disgusting.
Harassment and false accusations should be punished.
I'm glad Sombrella doesn't answer to the hatedom (screenshot ;) ), this is the best answer: ignore them.
