Noticing how post #2613915 is essentially lineart done over another artist's sketch (post #2195062), with minimal change to its composition.

The uploader did not explicitly define it as a color edit nor did they link to the original (but did name the original artist,) and attempts to reap credit by linking to their Twitter in bold letters. I understand the first two points can be fixed, but the fact the uploader didn't do it first makes me question their intent.

Should it be flagged, or am I just being salty? I don't like that some can piggyback off other's work like this, it doesn't feel transformative enough.

Added a source, since the uploader decided not to.

I'm not sure if this counts as a trace or not, but I personally think that it falls under the "low quality edit" section of the uploading guidelines.
I think, it actually got worse since the previous attempt.

Speaking of what is considered traced, what about rotoscoping?

https://en.wikipedia.org/wiki/Rotoscoping says:
Rotoscoping is an animation technique that animators use to trace over motion picture footage, frame by frame, to produce realistic action.

Especially given animations like post #2614153, which is essentially a frame-by-frame trace over a real-life porn video but changing the people into the comic's anthro characters.
