A bit of an update/thing people might want to know.
Whenever you register on a gamesite, you usually give an email and a password (or username and password). If you use the same combination on fanforums or anywhere really where you need to register, it can cost you.
Professional black-hat hackers (in this case guys that sell the information/logins/etc) have no problem with hacking into a fansite forums, as these don't have the security options companies do. The information they retrieve will be tested (automated scripts with PERL mostly, available online) on hundreds of sites from banks, games, anything that's worth selling, email, etc. These guys usually have your username used there, password used there and the email registered with there, with 'there' being the hacked site/database.
The point I'm trying to make here is: use different passwords. Easiest is to put them down in a wordpad file or anything similar or use a set of at least 2, where one is for generic sites and one for email and the like. Even different user names might help.
Not sure if I voiced the point correctly, but I did my best.
@anyone having bad ideas after reading this: all information is available by an easy google search, so good luck 'hacking'. If you're curious: have fun.
