Yes, someone definitely could. But also, you have to assess who your potential adversaries are. If you're very worried you would have to be very careful and could publish almost nothing online. You need to think about that balance for yourself and your case.

This is perhaps only a little more useful information than what you could get from someones LinkedIn page. However, there you could possibly also get a network of contacts which would be more valuable. If someone would target you and you specifically for something fraudulent, they would probably start by looking for you on LinkedIn.

I would say this website, if not posted here, would probably be less discoverable than the persons LinkedIn profile.
