how do these old roblox sites affect the official roblox site in any way?
Some of them like Graphictoria were using roblox's assets without permission.
When the site was up, you could upload your own shirts, and it used an exact copy of the shirt/pants template from roblox with some words changed. Although they weren't hurting roblox in any way financially, I would be pissed off if a group of young adults just took my stuff without asking.
