Don’t confuse ssl security with database integrity. SSL it’simportant when you surf the net through inscure connections like a open wifi, but not when you are at a private connection or with your phone.

The browser warning it’s only a warning. The LFF admins can go for a SSL certificate (there are very cheap for not commercial sites), but it’s a weird thing.

Database integrity it’s a task for the admins of the site. And it’s better kept on some sites than others (even Facebook had some problems not long ago)
