So that is the main reason why those platforms are not allowing users to use the TOR browser, only because the browser hides our Ip address.Of course, many platforms don't allow you to use the Tor browser, because the Tor browser will connect to a proxy server, so it can protect the privacy and anonymity of your IP address, any site you visit will be difficult to track, there is no history. Any website operator will easily know that you are using the Tor browser.
You are right, since tor browser hides our PI address and our identity those online money earning platforms don't allow use to use it. and yeah they don't also allow to use VPN.Tor is VPN and it masks IP . Money making sites want to make sure that the users are truly humans and are verifiable. With Tor, it is easy to create multiple accounts which will invariable affects business of the websites.
