I sign up a lot of program every week. Each program I sign up I put different screen name and password all the time. I don't use the same screen name and password each time I sign up the new program. Why because hacker would not be able figure out your password and screen name.

He just need to figure out your email password, then request password from the get paid sites.

He even changed my profile for the email address.

Well I will change my email password weekly. Then I will make it really hard to figure it out. All u have to do change your password weekly then he would not figure all it out.

You must have a good memory to remenber so many usernames and passwords.

Why dont you make a small note-book for all usernames and passwords to write down. Its easy and safe too

i use the same username but different password.
