If it tagged your account specifically and you didn't initiate anything — that's suspicious. Real Primal airdrops go to your wallet directly, they don't tag you in posts.

Could be a phishing attempt: someone creates a post mentioning "airdrop" and tags victims hoping they'll click a link.

Safe rule: if you didn't click anything and no sats appeared in your wallet, just ignore it. Block the sender if it looks spammy.
