The only legal way of hacking an account is through government services when requested by suspicion that you may be involved in something, for example hacking terrorists' accounts is legal as long as you're working for the government services responsible for these actions and have a clear notification on that you are allowed to do it.
Otherwise no, there's no legal way of hacking an account, be it on Twitter or any other social network.so you can HACKSTAR010(at) Gmai| .com contact who has license to hacking and spying onlineWhy is my girlfriend so?
