Whoopsies, nearly forgot my proposal! Apologies for triple post @_@
Proposal: Hacking
If you successfully end up figuring out somebody's passcode, you have "hacked" them. Once you have hacked someone, you have 3 options
1) "Spy". If you go this route, your target will never even know they've been hacked, but all you can do is simply see what their ~ATH code is, and any changes they make to it. What you use this info for is up to you
2) "Modify" Selecting this option will immediately alert your target that they have been hacked, but not who it was that hacked them. However, you are able to freely edit their ~ATH code, until your target figures out your identity. They can freely see what you're doing to their code
3) "Lock-Out" You completely steal their ~ATH code, and replace the passcode with one with one less digit (an ~ATH code that's been locked-out once has a 5-digit passcode, if it's hacked again it has a 4-digit one, and so on until it stops at 1 digit). The code is still under the original owner's name for the purpose of guessing their passcode. You can freely change this ~ATH code, but the one you stole it from is unable to see any changes you make. If you go this route, they will know exactly who stole their ~ATH code, and will probably be out for revenge!
