For example;
- Browsing with browser private mood: I do this with chrome by using the incognito mood. I thought I was safe but little did I know that my ISP still see my browsing activities
- When I use VPN, I had the feeling that I was so safe and my data save till o_e_l_e_o said this Re: Identity Security: A Newbies' Priority
- More often people enjoy using known and popular search engines like Google instead of using anonymous search engines
All common mistakes that people make. Private browsing does literally nothing to protect your privacy, VPNs can hide your IP address by do not provide anonymity (Tor is a better option), and anything owned by Google is a terrible option. DuckDuckGo, Startpage, or Searx are good alternatives.
It's probably true that most of us have already leaked a metric tonne of information, and that information has probably reached someone who you never thought would've been able to gain access, but the older that data is, and the less its being renewed the less valuable it is.
Not only that, but avoiding linking new data to old data can be a very valuable exercise. Let's say you start searching for cancer symptoms. With a clean slate, maybe the data brokers know that someone in your IP range is searching for cancer symptoms and can't do much with that information. Without it, perhaps they know your full name and address, and then pass that information on to some insurance companies, and then suddenly your premiums triple in price. Or perhaps you are sending some bitcoin to a political party or cause that your government doesn't take too kindly to. With your new data being linked to all your old data, then your government agents maybe pay you a little visit. With your new data being separate, then perhaps they can't track you down quite so easily.
What I've found a useful tool over the years is using the feature of adding a "+" to your email address.
It's not a bad idea, but a better solution is to have different email addresses for different purposes.
However, all being said, I think the new crypto browser by "Opera" will be of better use here
This browser is designed to integrate wallets and NFTs directly in to the browser. It is not designed with privacy in mind, and it is based on Chromium, so I really wouldn't recommend it.
