So today, I went onto an old laptop and went through the history to delete stuff, so that my mother could use it. Found some decent art, and favorited them... Only to find out that I was logged into an old account I never used. So yeah, basically I had to open each image, unfavorite, open them all in different tabs, log into this account, F5, and re-favorite.

So if you noticed two similar accounts favorited your artwork, that's me. Just made a silly mistake :P
