Artist Issue

So https://sarah14109.lofter.com/post/4c608c46_2b6b56df0 contains this media asset, by banned artist Lyoo_(cacj5482). However, it is a duplicate of post #5918272, which is stated to be by another artist entirely Gajyago. I'm not seeing any clear similarity between the two other than a similar artstyle, so what's going on?

Same artist.
Lyoo display name on Lofter is gjg.
Multiple images on https://gajyago.com are in pixiv #101193680 (lyoo).
twitter #1554996032743694336 (gajyago) has the watermark from lyoo.

Time to go put in a ban request then. Thanks, I wasn't sure if they were the same artist or not.
