Paying emporium 10 dollars or imvu pro 50 (lol) is, in other words, burning money.
They can't protect you from such things, because they never did anything special in the first place. All outfits, who is wearing them, this is all written in the link of each "products in scene". If someone wants to see your outfits, and they really want to, they don't need to use such websites, it's pretty easy otherwise.
The links start with the avatar ID, then what said avatar is wearing: ID by ID of each product.
If you don't want to open each ID everytime, you can use any website that "unhides" outfits simply by exchanging the blocked ID, that said, the ID that was paid to be "protected", to one that isn't. Tada! There it is.
Because they can't really protect you, they protect said ID. If the website thinks is another person using your outfit that you paid to protect, there is nothing said website can do. 10~50 dollars burned, hands down.
Not to mention that, say you pay for this bullshit protection, what happens when another website that unhides outfits appear? Pay another fee? Better to deal with it.
