Is uploading avatars for others a bannable offense?

Sorry if this is the wrong section ! I wanted to ask for help on clarification of avatar uploading TOS. I swear I read a post about a week ago from Tupper that cracks down on avatar uploading for other people, and saying that it was breaking TOS. If anyone could link that to me, I would appreciate that, since I help run a VRChat avatar server and would like to make sure everyone is following guidelines.

If it’s on these forums you are able to see every comment made by Tupper. Start there? Uploading avatars for someone might give VRChat an indication that it’s the same person behind the accounts, just a speculative comment.
