Good catch. Pretty lame scamming attempt. Whats funny is Blockchain.com really did hold a XLM giveaway back in November... I haven't heard from them yet but I did get this email from them:
Congratulations! You're on the waitlist.
You'll hear from us via email as soon as it’s time to claim your XLM.
In the meantime, check out updates to the Wallet. Not only have we added support to send, receive, and trade XLM, we’ve also added hardware storage with our Lockbox launch and rolled out Swap, our next generation trading product with best-in-class liquidity and execution.The email came from
noreply@blockchain.com.
All they asked for was my email address; they didn't even make me re-log into my old wallet, just send them the email address that belongs to my blockchain.com wallet.
This is why its an important reminder to always verify the legitimacy of the website that is hosting such a giveaway.
If anybody's curious, the actual XLM giveaway link is here (looks like its still ongoing apparently); its for $25 worth of XLM:
