I am someone with a real name that is relatively common first+last name, iirc about 1:50000 or so in the US, there are lots Michael Ryan's out there, I've met a couple unrelated to me. And a handle (tracker1, azTracker1, xTracker1) on various social media, and a *lot* of them are not me.
While interesting at best, this is dangerous at worst. As long as you're only testing for actual indicated names on other social platforms, then this *might* be okay. If you want real verification, most of them have some sort of OAuth interface that you can use for only name/email identification matching. If you're using a self-registered interface for what is "public" you may be violating TOS (which can be interpreted as a crime in the US.
I'm not the one who down-voted, but can completely understand why one would.
edit: Just an example of how mangled things get, the main image/job title is not me, but other pieces of information are me. https://rocketreach.co/michael-ryan-email_25502930
