Wow, the dude has been around since May 2017 and has never seen a confirmed trigger.
Like a guy's first day on the job answering, "well, in my experience at this company..."
Lol.
I was inquiring, not saying that there isn't any.
But I did research it a little, as I do use third party checks, and the reports I saw focused more on 3rd party attached bank accounts, and were wishy washy about the checks.
