The forum was hacked recently. The dump contains emails & hashed passwords as of Sep 2017.If you don't use a randomly generated password for each site you visit, you may want to change your password here & on other sites you shared this password with.If you use a password manager & a long computer-generated random password you aren't at risk.If you would like to start using a password manager, so that you don't have to worry about leaks like this, popular ones include www.lastpass.com and www.1password.com edit: PS accounts are not effected, although in 2016 PS was hacked by the same person, so if you somehow missed that announcement, take caution
