100% SCAMMED!
There’s no job. But you can probably relax. No damage is done except to your pride. That scammer isn’t interested in stealing you identity. He’s only trying to get you to sign up for some credit reporting site using his affiliate link. The only thing he’s after is the commission he would receive for getting people to sign up under him.
You might want to take note of all those big yellow banners on Craigslist warning about jobs scams in particular or any other scams in general. There are no real jobs and those asking you to provide a credit report or the report number are scammers/identity thieves.
After you signed up for the credit site, you can expect the scammer’s next email would say: “sorry, the job is filled”.
You might as well expect more emails from that scammer and others, now that you are on his potential suckers list. He will use various emails, from various different companies, with stories about great jobs, sexy signals etc. Don’t respond to any.
