As someone who has had my prompt stolen, it really fucking sucks, and you (or anyone else who tries to talk to this person and gets shut down) should report this person to cherubplay. They might make a new account but hopefully that will get the message across. Send the cherubplay tumblr a link to the chat and they’ll take care of it.
Don’t steal prompts, guys. Don’t even “trace over” prompts and edit them just enough that it’s not complete plagiarism. Take the idea and make a new prompt of your own, if you like it so much.
