i (and whoever else has access to my canvases) get notifications of people joining/making changes to my canvases and when i join the canvas there is no one there, but it does show that a different account has been on there. when i clicked on said account it said that they were created the day that they joined the canvas, 0 following/followers, 0 posts, etc. the pfps are usually a stock picture that you get automatically when you join magma, like a shark, chick, or cat. their display name is "Anonymous" and username "@user-" with random letters and numbers after the dash.

im not entirely sure if this is a bug, hacker, or just lag, but its really creepy, especially when everyone that has access to the canvas (via invite/link) is on and someone just appears.
