There is zero privacy using a VPN when they have all your details on file from a credit card transaction. Cryptocurrency is the only private form of payment online period.
These guys are total hypocrites, they will likely be selling your online activity to anyone willing to pay so they stopped accepting crypto because if you pay with crypto they cannot profit from your data easily.
Here is their chatroom if you want to stop by and let them know what you think about this
No one is going to go through all that effort to make sure it is me doing the browsing for marketing purposes. You are talking about thousands of hours of work.
I am not talking about doing anything criminal. I am talking about using an easy anonymous form of payment to thwart the vast majority of general spying.
The point being is if your VPN refuses to accept crypto it is most likely because they are selling your data and they cannot sell it for any good price if they do not know who you are explicitly.
You are talking about plausible deniability, so I assumed this is in relation to law enforcement.
It's 10-20 manhours and most of it is letting an expert read the logs. I worked on the ISP side of such cases, it took us 1 minute to provide such data.
I was speaking of plausible deniability on the social level not from a criminal perspective.
A VPN would stop them in their tracks because there would be no logs to read except you connecting to the VPN on the ISP side.
You can also use a VPN -> Tor -> VPN in which case it is almost impossible to trace anything unless you examine the whole internet connection map which is thousands of hours of effort.
