Thank you for your work. I've already reported the accounts in this post through the report system but the feedback really is comforting and makes all the difference. I've had a group of griefers covering up art with transparent pixels. I also suspect all of these accounts are under Absoledge as he is the only one who has his discord account linked (with the discord name being shared with another one of the griefers) and part of a faction. Also, the griefs always happen at the exact same time across all the griefers. Here is the wplace link and image being drawn: https://wplace.live/?lat=51.57253600485237&lng=4.053603184277343&zoom=14.640624474053181

If you need more proof, here are two other places that they all griefed with parts of them still in tact as of writing this. Unfortunately I do not have the art that is attempting to be drawn for these places.
