Well as I am sure that you have heard by now, never give your password out its a scam. Even if people read this they still may find a "hack" thath they feel is legit, so here are the most common scams I have seen.
1. I invented a hackng program that can get all your stats to 99 and give you tons of sarodomin platebodies (often times this example is used though others are common as well) send your username and password to SOMERANDOMEMAIL.
2. I found a way to hack into the runescape servers and find their password recovery email (usually spiced up with words to make it sound legit) if you want anyones pasword just email SOMERANDOMEMAIL the following.
08917094745-2)#($(your username)094902834-23094-092
)(*&#@()*$&219812(your password)94908312498(!#$_)*$#
029317!@#)(*()0133(victims username)8914098312)(*!@#)
3. My dad (cousin/brother/me) worked for Jagex but was fired for giving some items away now (he/she/me) has inventerd a program that will soon be released, but until then send your username and password to...for anything you want in the game.
4. I made and item dupe find it here (link to infected site with a keylogger)
5. I am zezima I will give you stuff just send me your username and password requesting what items you want.
Please, don't fall for any of these, or any situation where you are asked for your password.
Just play the game honestly and gain skills the normal way, searching for hacks will just waste your time and most likely cause you to lose an account.
Hope this guide has been helpful,
