There is someone on Twitter claiming your art is theirs, lying to the RP community. They claim it's their OC and circumstances they came up with.
However their account is set private because they believe artists cannot report them like that. But that is not true.
You can go here to file a DMCA to have the art removed from their account.
Please help fight this art thief! they steal countless pictures from many artists and only with a lot of reports can they be banned
