The creepy billboard in Allston, explained

• As your resident TikTok addict, I’m here to explain who he is and what he’s doing.

What’s happening: Trevor Rainbolt, AKA @georainbolt the "GeoGuessr guy,” has amassed more than 2 million followers on the clock app by examining images of parking lots, dirt roads and other mundane items and spitting out the exact location of those images.

• A CAPTCHA image of some parked motorcycles? He traced it to a since-removed bus stop in Paris.
• A distorted image of grass? Turns out it’s in Eswatini.
• A random tunnel? We’ll let you see the answer for yourself.

Back to the creepy billboard. This shows you what he would look like if he were tracing a clue to this portion of Brighton Avenue.

So who paid for the billboard? And why is it here?

• Rainbolt tweeted that he bought the billboard so he could “be on street view forever.”
