(adsbygoogle = window.adsbygoogle || []).push({}); I've bought an id from eBay and it was already banned then I've bought a second one from a guy on YouTube who sold them and I sent the money and still haven't received it. Is there any legitimate service/seller I can trust not to rob me and give a genuine id?

The sale of CIDs is not allowed on NGU so you're best bet is just to keep looking around and hope you have better luck.

NGU doesn't allow for buying or selling CIDs, sorry. You'll have to find another place, but be wary of fake cid sellers.
