Who is Sam Porter Bridges when he's at home?

I asked this question because someone was using that name on another site a couple of years ago, and I wanted to find out who he was because I had reason to believe he was a sockpuppet account of a known troublemaker and I wanted to expose him.

Any luck doing so? I imagine you Googled the name and only came upon the protagonist of Death Stranding - that's what I thought you meant.

His account on that other site seems inactive now, so maybe someone else has exposed him already. I wanted to be the one to do that.
