How to hack someone account

Can you help me if you do i can give u 20k nx if it works

It's not exactly hard, go download any keylogger/rat of your choice. Generate a new one and bind it with some other program/tool, get him to download it.

The hard thing will be a). to get it into his computer and b). to get pass his AV/firewall. For the latter one you'll need a FUD crypter or to write your own keylogger/rat. For the first one there are no magic solutions. I would never visit links or download files that someone I do not trust sends me and even when it's people I trust I am generally cautious. Perhaps this guy is less cautious but then again he just might not be.

Many of them are rather noobfriendly and easy to use. I hope you mean you spent two years on learning to develop them yourself, cause there's no way it would take anyone two years to learn to use one.
