I personally believe it's likely. This is what I know.
1. Someone on the server contacted me saying they know house irl, or something to that effect, like play other games with him? They said house is a 14 year old boy. Not proof.. I know. Could be bullshit.
2. I called him on the accusation, and House posted a photo of themself. The photo was CLEARLY a heavily edited faceswap. There were tons of hallmark signs on the photo proving it. I made a post detailing all the edits, but you don't need a professional to tell the photo is fake af. House immediately got staff to remove the post.
3. House was asked to provide a signpic (a photo with 'olympus' written on their hand. That's very hard to do with a faceswapper. He claimed he would. Never did. He claimed he would get on discord video (offered, wasn't asked), and when I accepted, they backed off.
4. House then posted a different photo of themself where their face looked entirely different (this one wasn't saved). Only the hair was (remotely) the same.
5. House then reposted the original photo but was heavily edited to remove all shadows, the second nose, ect. (2 days later. They took two days photoshopping the fake marks out, but ended up making it look even faker).
