if it really had been bias then I would only have done it a couple of times and have been lucky to not get my credit card details stolen, but I've done it several times and it still didn't happen to me. The stories I keep hearing about people who get scammed is far from unusual, there are tons of people out there who are paranoid about getting scammed or having their details stolen and think twice about using sites that don't have a very good reputation, meanwhile, retard me goes on the internet, finds the shadiest site you could ever come across, order products from them and don't even get scammed. I mean, one of the sites I used was so suspicious that the transaction made from my bank account to the site had a very suspicious name that didn't have anything to do with the site I used, I think it was related to female cosmetic products despite the thing I ordered not having anything to do with that.

Incorrect, it's still biased as long as you don't know the numbers from both groups.

Let's suppose that 1% (randomly selected) of buyers of a certain shady site got scammed. It would be completely normal for a certain normal user to never got scammed even if they did dozens of orders there (0.99^50=0.6 meaning there's 60% odd they won't get scammed for the first 50 orders). On the other hand, if the site is popular it would still lead to the tons of people who got scammed and it would say nothing of their retardness in comparison to that user, only of their luck.

as far as I understand about what bias is, then it would be cases where there would be a misrepresentation of, in this case, the likelihood of getting scammed. The more you do it and don't get scammed, the better the representation of the chances are. I just feel like there's a lot of people out there that spend a lot of time being worried about using shady sites, and I don't worry about it at all and don't get scammed. Feels sometimes like it could be boomers and their ideas about how the internet works affects how people see certain sites that don't seem trustworthy, and they avoid them based on that idea.

Truth is, there's actually tons of different people that despite having sites that could be considered shady and aren't used very often, they still want to run a business and do things honestly, there's actually no real way of telling whether a site is going to scam you or not, you can't really figure it out judging just by the way the site looks, or even things such as reviews as they could also be faked. It probably also has something to do with the fact that I don't really have a lot of money that can be stolen from my account, but it really makes me think about things.
