Welcome to the Steem blockchain.

You'll want to contact the people behind @cheetah to confirm you own the content on your blogspot. They're a service on here that checks for people stealing content and posting it as their own. Since you cross-posted your content here, their bot caught the duplication.

Though, in one sense, the bot totally linked your blog for readers. :P That's something you probably consider doing yourself in the future.

Wish you luck on the Steem blockchain! It takes a bit to get used to at first.
