Small ideas for LO.
1. If you block someone their avatar is set to the loading default avatar. Or blocking anything made from the symbol editor.
2. Account blocking to block all there alts with one block.
3. If the user is perm banned or deletes their account they are removed from the block list so they don't take up space.
4. Client-side ignore list. This will allow players to have a small file on their own pc so it doesn't take up room on your servers. I don't want to remove one troll to add another If I block you I have a good reason to do so.
An added note.
I would love a streamer mode where you can block all avatars by default unless they're your friend. Or blocking anything made from the symbol editor for non-friends.
Extra note from Saxtus on Discord.
If you block someone their car is also set to a default type of that car.
