I have reason to believe Little Cute Thing/Littlecutecorpse/Disease & TrashOfThisGalaxy are the same person.
The TOTG in the Pretty Blood Discord was an impersonator - Santu pretending to be him as a prank.

The TOTG Inkbunny, however, the primary source, I suspect to be run by Disease. Refer to the evidence below.
One art piece, "Edgy bunny", was posted to the Pretty Blood discord by Disease himself, as well as the TOTG Inkbunny. (Although, not to his Newgrounds.)
The latter predates the former by one minute, and even after reverse searching it, I could not find any older copies.

Due to the nature of several things in the rest of the TOTG gallery, I am concerned for Disease's integrity, if he really is behind the account.
I will not be directly linking it here for now due to many of the images being pornographic (and appearing to be non-consensual as well some of the time). You can stick the username in your browser if you're curious, I guess, but please watch your step.
If you are Disease and you believe there's been a mistake, please Private Message me on Newgrounds @lurkingdeviant1010
Thank you
