With a certain method, the phone isn't blacklisted. You can go around this

Good to know there's a working method.

The actual phone carrier has a pool of blacklisted IMEI numbers that're provided by (In this case) Google. Upon trying to activate the phone, the carrier will see the IMEI Is flagged, hence will not allow activation. I assume your method does not flag the IMEI number.

Yes. Rather than focusing on the refunding part, my method focuses more on the se'ing part

Clever, namely when devices of this nature are Involved.

As such, the device will remain active, so too will Its IMEI number.
Good work.
