Definitely a scammer in my opinion. It warns you that he's a newbie at the top, but then he creates that bullshit addition down there saying that it's genuine because he's a hero member (which he's not). That kind of lie should be enough to assume he's a scammer straight away.
Since he's talking about using escrow though, if you're actually intending to buy something from him you
could go on, as long as you receive
every message from the escrow directly and not as a quote from him, you verify the PGP key, you check the name to make sure it's not phishing, you don't click on any links, and many other generic warnings about scammers.
Personally, I wouldn't bother trying. Just add him to your
ignore list and delete the message.
