I received a very small deposit of XLM today in one of my stellar accounts, and the memo of the transaction read "Airdrop invite xlmline.com". Visited xlmline.com and it legitimately looked like a stellar airdrop announcement. I almost fell for it until it asked for my private key. A quick google search did not return anything about a recent Stellar airdrop either. Anybody else seen a scam like this before? I can see how easy it would be for a noob to fall for something like this.
Yes, this is sadly a common way of spreading scams. Some wallets even warn if memos contain URLs.
There are NO giveaways or STACKING opportunities with stellar and if someone asks for your private key it's probably a scam.
