Public apology

Hello everyone, I would like to ask everyone for a public apology for having published drawings that were not mine, I just thought that the page accepted google's own drawings, because that is how they explained to me when they invited me through the link, at first I did not understand why negative comments because I thought I was doing the right thing, but now I know how the platform works, I ask you for a public apology and please if you could tell me how to remove the old posters I would appreciate it. Excuse me please. Greetings to all
