Reviving a very old deleted site - worth it?

I was Googling my name as I do from time to time, and I came across one of my old sites with me still listed as the contact.

I stopped updating the site ten years ago, and the domain would have been deleted a year or so after that. Someone has bought the domain and added the old content from the Wayback Machine I presume.

It never had the strongest metrics, but all links were white hat and niche relevant. Is it actually worth reviving an old site after so many years or is this just someone that doesn't know what they're doing?

they definitely know what they're doing. People who have no clue about SEO don't use WBM (they don't even know what that is), so yeah, the guy is using your site for its backlinks most likely
