The 2+2 forums are dealing with some bad guys who are trying to brute force people’s passwords. In other words, some guy somewhere is running a computer program that probably has a very long dictionary of commonly used passwords and systematically tries a ton of different passwords for a ton of different accounts on 2+2. These types of attacks are essentially preventable by website administrators (and hopefully 2+2 will get its act together soon), but they’re still quite common.
If your password is uncommon (e.g., “kfag4;6-lkjghaa” and not “mypass”), it’s likely nothing to worry about. If your password is in the list of the million most common passwords, someone may very well get access to your 2+2 account as a result. (You should go to 2+2 and change your password immediately.) Worse still, if you use the same password for your e-mail or for a poker site or your bank account, you might lose money as a result.
So, I just wanted to quickly share some easy ways to choose a decent password. I got the basic idea from an awesome xkcd comic. (BTW, xkcd is really cool, and you should check it obsessively on Mondays, Wednesdays and Fridays.) Remember that the goal of a good password is to be both memorable and extremely hard to guess.
