I just went on the site. The 'top' profiles include usernames like `elonmusk`, `loganpaul` and `arianagrande`, next to an icon saying they're "waiting to join". This sounds like a lie right? Unless there's such demand for this site that Elon Musk and Ariana Grande are waiting in a queue to get in on the BitClout action?

Exactly — “waiting to join” would be a lie if Elon Musk did not initiate intention to join the service. And Elon Musk does not wait in lines...

It’s eye rolling deceitful marketing.

That sounds like you're reading "waiting to join" backwards?

“Reserved, unclaimed” is a classic dark pattern.
