everyone has their own choice regarding how to secure their own account. Forcing the users to adhere to the most extensive recommendation of digital security is advisable, but that did not close the possibility of the user leaking their own data due to they did not understand the reasoning behind them. So if the users themselves have better precaution and comprehension about what security features a platform has, they would willingly use it for their own benefit, not because the platform forcing them.
As one of the security precautions, if you try to brute force an account on the Roobet site, you would see this security measure prevention, "Invalid password. Maximum 15 attempts per 5 minutes."
I agree with goldkingcoiner, this isn't some liberal issue where you want freedom of being hacked if you are not careful type of deal, that can't be done, it's just not normal and shouldn't be the issue. I believe that we shouldn't be given that option and 2FA should be forced to players so that it would be safe, otherwise you are just being horrible about the situation.
I agree that not having the freedom to do whatever you want is upsetting for some people, but this is there to protect you and if it's a good intention thing then you should be able to understand why it was done. It's not much work neither, setting it up takes maybe 1 minute max, and it takes extra 15 seconds to login.
