Be care to keybase airdrop that promised 500 xlm. Is a scam.
Did you even bother to do proper research before bringing this claim tagging it scam? It's not a scam, many people did multiple accounts and were banned from the airdrop. Some countries too were restricted due to cheating. If you actually did the airdrop and you have the yellow XLM badge, do wait for your turn to receive since it's done alphabetically with respect to username.
