I actually hate it when a website does that, especially when it doesn’t let you download the application you want because your OS is not compatible. For example you wanna download some windows software to run it with Wine/Proton and the website detects you are running linux and does not let you download. I always need to spoof my User-Agent string to get access.
How do you pay the VPS Provider? The Cops can simply go to the VPS Provider and ask what Bank account or paypal is linked to the Account who runs the Server with the IP address they tracked. And what if the VPS Provider is logging your traffic? They can Monitor anything that leaves your VPS (their network) because a VPS is just a Virtual Machine like KVM thats why its called VPS = VIRTUAL Private Server. OPSEC my friend… I think you are safer if you just use Mullvad and pay with XMR and only access the mullvad site from Tor. (I know i am paranoid xD)
