When I used to go on the Wikipedia page, and I haven't gone on the page in a while, there used to be some guy who was doing my page and he would say that he was my cousin and I was going to be doing projects with him. I don't know who this person is and I don't have a cousin by this name and this person keeps saying that they're doing projects with me. It's so weird.
