If it's not the same person there has to be some connection between those two, right? So what happens if Mr. Innocent gets inundated by phone calls or gets a police report filed against him or just googles his name one day? I'm not saying it's right or wrong to tie a person to a scam that way, just trying to follow this assumption further.
Here's the theory:
The connection is that he one time got called "dicemasterflash" in an instagram photo. Maybe he's a fan of
80's hip-hop and had been playing craps at the casino with his buddies the night before, so as an inside joke someone tagged him like that.
In that case he's not going to google his name. He'll just be surprised by an angry mob one day and have no idea why they're
baying for his blood.
TBH I don't know much about how all these newfangled sites work, but I think the tag linked to an instagram page that had been deleted. Just like why a "hacker" would delete "victim's" twitter accounts etc, why would an innocent unrelated person delete their instagram account? Yes, there is a chance of that happening accidentally, like there is a chance to lose 40 straight at 49.5...
