This has been discussed multiple times in Meta aection. But let me give you my opinion. Actually the security of this forum is totally secured. No one can hack your account unless those hackers already got your password. The safety of your account depends on how you take good care of your private information such as passwords and of course avoiding malicious sites than can compromised your account.
These "hacked accounts" issues lately are not actually hackers hacked your friends account. I'm pretty sure that they are just victim of Phishing which only happens if you went to a malicious website or fake website of Bitcointalk
which is the owner's fault. A lot of members are already here years ago even me and as you can see, we didn't encountered such security issues. All I'm telling is the security of the forum is working fine and there's no much problem about it. About the 2fa, it would be a great idea. But Admin has some reasons why not implementing it (who knows, time will come and it will be implemented).
Just let me give you these advice to avoid being hacked.
- Make sure that your password is strong that uses a combination of Capital letters and numbers not just password like "123456789", but it's up to you.
- Don't just click unknown links especially sent through PM from unknown users.
- Use some trusted third party security like Malwarebytes, it will help you detect some hidden virus from your pc that may cause to get your personal information and it also detects phishing sites.
- This is obviously, Don't just give your password to anybody.
- Take good care of your account.
These are just some tips to make your account secured. There are still a lot of ways to do to enhance security.
One more thing, be careful when filling up Airdrops forms. I have some feeling that they're putting phishing on them and usually the victims are Bounty hunters. If you're a bounty hunter, then you know what to do.
