RPGNERD'S PROFILE

I saw this art theft earlier and I wonder if this is really okay?
Someone has pointed it out already, but I can also clearly tell they are rips from Chrono Trigger and Final Fantasy VI. This guy also deletes any comment that points this out.

This game exist here on this site and is marketed as "Commercial". He also asks for money on Patreon. He was also very clear in the comments that they are not placeholders.

How should I proceed to report it?
