how do you hack someone's twitter account?

[Chip]

Breaking into the web database of a major tech company like Twitter requires years of knowledge on networking, information security, programming, and psychology*, not to mention it very often also requires physically trespassing areas.

It's not like it is on TV, where you just type the right magic phrase into that mysterious black box known as the command prompt and *poof!* you get instant access to whatever you want. Nor is it as simple as downloading some illicit "hacking" program, which more often than not will do nothing but let real hackers break into your machine.

Point is: While I completely sympathize with your situation, there is absolutely no realistically way that anybody on Yahoo! Answers is going to be able to help you. It has nothing to do with the legality or morality of the thing - it's the simple fact that we're not college professors.
