I need some advice or help

Please understand that the tone is a bit strange since we are using a translator. Is there an effective way to ask Archive.is to erase the things that Archive.is has kept? Today I archived one site, and there was another person's work. And it wasn't my site. Do you understand what is happening? I know, he was stupid. I'm reflecting on myself, but I really want to erase it. If it's impossible, you don't have to erase it. If there's really no way until the end, it's actually okay to just cover it up. Do you happen to know a good way?
