ThisPonyDoesNotExist should not have artist prefix for practical reasons (not aliased either)

I’m not ready to grant creators’ rights to computer programs  
Suppose I want to hide images generated by ThisPonyDoesNotExist but want to see artists’ potential drawings/redrawings of designs; Philomena’s search/complex filter currently has no way to exclude particular substrings from a wildcard search, ie. you cannot conduct a search for “an artist:* tag that is someone other than artist:thisponydoesnotexist, in addition to artist:thisponydoesnotexist”. Thus, it would be more practical for the tag to be un-prefixed.
 
It also must not be aliased from the tag with the prefix, because search/filters will treat them the same and will still fail.
 
P.S. Using source_url:\*thisponydoesnotexist.net\* would be a way around the problem except many of the images aren’t being tagged with a source…

Images that are edited from a generated base image should be tagged edit in addition to artist:thisponydoesnotexist, so you can filter (artist:thisponydoesnotexist, -edit).  
Images that just redraw a pony design that was initially created by the network shouldn’t be tagged with artist:thisponydoesnotexist at all, because the image would be entirely the artist’s work. We don’t tag images of OCs with the name of the OC’s creator. Maybe an additional non-prefixed tag can be added for those images, but I don’t know if the origin of an OC should be tagged.  
And according to current ruling, every drawing of a mane 6 character are now considered new OCs based on the AI. /s
