Today around 12:00pm EDT, a post was uploaded to r/whenthe by u/concussionmaker_91 about how despite their multiple privacy measures, Reddit was still able to ping their location and show them an ad about a business in close proximity to their house. Then, in less than 2 hours after the post when live, their year old account was permanently banned. 
Redditors in the comment section used a website called SnooSnoop to see if this account has done anything malicious in the past that may be grounds for a ban only to find nothing. 
I don’t think this is a mere coincidence and some comments I read on the post may be there to dismiss the situation.
I’m currently working on archiving the post and comments in case Reddit decides to try and erase this entire situation from the web, I’ll attach the files when I do.
Before we start rolling out conspiracy theories and such, let’s all apply a little Occam’s razor to this.
The simplest explanation is that OP is full of shit.
The simplest explanation is that OP doesn’t have good opsec, and got a few tracking cookies after deleting cookies, before setting up their proxy/VPN. Then, on the VPN, the advertiser recognized their VPN IP address, and chose to exclude that from generating location data, deferring instead to the location indicated in their existing tracking cookies.
Privacy is hard. The system is rigged against privacy. You have to do everything perfectly, because one simple mistake could leak your IP address.
Hanlon’s Razor seems much more apt, suggesting OP’s incompetence rather than malice
Hehehee
Actually though, theat’s not truthfully Occam’s razor. Occam’s razor requires the easiest answer with the least assumptions, which would be, that they’re using their tooling wrong.
Finally, someone uses Occam’s razor correctly! The least amount of assumptions is the right verbage.
