Quite a few of you have gotten the "You're locked out of LJ because your password sucks." and complained about it.
1) This had been announced in
news last month, so you should have known it was coming. And if you're not watching
news, you really should.
2) If your password is insecure, then it puts everyone at risk. Not only you, but your friends as well. You know how some of your friends post their contact info in friends-only entries? Well, if someone breaks into your journal that contact info won't be that safe any more. Not to mention, of course, how someone could break into your account to just violate the ToS and how you'd be into trouble.
3) You know, it's not very possible that someone will go and try to guess your password. People cannot do this manually. Machines can, though. There are programs out there that can check thousands of combinations per minute. So what does this mean? That a program can very very easily guess your password if it isn't a secure one.
4) LJ isn't doing this to piss you off. Why would they want to piss you off, after all? You're the clients. They have, however, to do anything possible to keep the site secure.
In two words? Do not complain because this was done for your and your friends' good.
