How very mature, and not totally childish.
Elon Musk tells advertisers: 'Go fuck yourself'
Now that most “normal” (i.e. non criminal entities) advertisers are gone, at least the crypto scammers still pay for promoted posts on Twitter/X, as well as the fake Gucci bag scammers, romance scams, low quality goods from Ali Baba/ Ali Express but with inflated prices, advance fee fraud grifters and fake NFT mint wallet drainers.
Examples of promoted posts which lead to phishing / fraud / counterfeit websites:


Promoted posts pushing fake counterfeit Gucci™ bags

Promoted posts pushing fake “survey” leading to wallet drainer
Promoted posts pushing fake “survey” leading to wallet drainer


Promoted posts pushing fake “airdrop” and “survey” leading to wallet drainers

Peculiar how much scammers have paid to x/twitter for ads, to get 3.4 million views in a few hours, given that both the domain certificate and ad were from registered on the same day

This promoted scam even uses Musk’s face to instill trust in victims

Twitter/X paid advertisement tied to domain registered via a temporary email address.
So this tells you something — this is a hit and run operation.
Whoever registered this domain does not plan on maintaining it for long or whatever.

Same Scam, different name.
