I'm wondering why don't they (admins...) warn every newly registered user about the possibility of hacking of their accounts and about some measures they should take in order to avoid losing their accounts...

Something like a little howto...

1) NEVER use a "secret question" option to recover your password;
2) Your foremost post at this forum should contain your BTC address - ADD A BOOKMARK to that message in your browser and NEVER edit it (neither bookmark nor post);
3) whatever-else...

 

I have no messages containing my address mentioned in the first post, I have a message with another my bitcoin address somewhere on this forum, but it will take some time to find it...
