My twitter account was hacked and spam posted. The password was one I've used for over a decade online. It was vulnerable to dictionary attack. Fortunately, my account wasn't modified, and I updated my password to something incomprehensible and unhackable. I also changed my Facebook and HTF passwords. Especially HTF, which used the same 10+ year old password. I also noted that Facebook has great logs of all the computers I logged in from, and let me disable outdated connections. Twitter: nothing. No idea where the hack might have come from (not that it matters). But it reinforced my preference of Facebook over Twitter for my practical needs.I recommend you change any simple passwords for high-profile websites.
