Someone is posting my art (Patreon)

This user here has been uploading my artwork Sonicateds User Profile | DeviantArt

from the patreon on Deviantart without my permission - I don't normally care about this, but considering that I use this patreon to have art stuff, I may need to change things up going forward and have private folders that only you guys can have access to or up my patreon requirements to view the art.

I'm getting sick of this.
