Yes, that is the correct way of verifying.
It has to be a well-established social media account (not recently created, with lifestyle activity matching the face of the person on Hive).

Holding signs can be easily forged with photoshop or by asking a random stranger to do it. Which happened on dozens of occasions on Hive.

Very strange reply.

Has time to post on Hive but has no time to add a single word to social media.

The third Facebook account that was given will certainly not be accepted either as it is not well-established - it has almost no activity and there is no history of the lifestyle of any person. The profile photo could have been copied and updated recently.

I hope that it is all a misunderstanding and that the account will be verified soon.
