I have 4 files on runescape but I cannot get into any of them. Can someone help me with this problem. If it is fixable, then say so and tell me how. If not then say so.

You mean you have 4 accounts and when you enter the password it says "invalid username or password"?

Ya, and I hate to say it but I think they were hacked. I got one back and found out that his mith stuff was missing. The other three I never got a chance to recover yet. I HATE SCAMMERS

Well what did you do on the accounts? The only other reason you lost your account is you did something you weren't supposed to do, got reported, then banned. And I think that probably how you lost it must have been either coinicidence or you saying something on RS2 that allowed enough evidence for your 4 accounts to be linked to one person. On the account you got back, what people were on your friends list?
