Because of your proven FALSE accusation, the artist was harassed and threatened. Now the artist has completely left the internet and shut down their accounts.

So no, sorry just won’t cut it after the irreparable damage you have done levelling a false accusation of using Ai with practically no real evidence.

Go look out for the artist - see if he/she still has a public online presence somewhere.

Apologise to that artist. Remember, the artist can decide whether to forgive you or not.

If the artist comes back, and moves on. Then people can accept your “sorry”, because right now your sorry means NOTHING.

Right now you don’t even have the decency to name the artist you wronged by handle or name. Just saying “I did something wrong and deleted it”, hoping people will just forget it.

Your lack of specificity and willingness to memoryhole the real damage you have done to someone completely innocent, is insulting.
