But I haven’t stated for a fact that it is not stored in their database but you have stated (without any evidence) that it IS stored in their database.
I think they could do it in Java but I don’t think Java is actually run normally on the client side. It might be possible in other ways but it’s not standard like I said. And I don’t think anyone has ever said on the forum that they sold a PC/laptop, completely wiped it and sold it to someone who then used it for Fiverr selling and that seller got into trouble because that MAC address had been used before. Though if a seller/buyer was thinking about doing something like that it might be worth asking CS to be sure. They could also post CS’s reply on the forum so we’d know.
You could also ask CS if you think they might be storing it so we can give that info to anyone who asks in future.
If Fiverr were running a .EXE on our PCs I’m sure they’d be sending the MAC address as I’m sure it would be easy through that.
Do you think fiverr unable to do this?
Also you create websites for your service. Are you able to easily get the MAC address from the PCs of the users who visit the sites you create?
