I know that if you have never been scammed it seems impossible that it could happen to you, but it can. I was never very careful about keeping my password secret until my account was finally stolen. Even if it seem unlikely that you will be scammed I suggest that you follow these tips:
1) NEVER tell your password to anyone, even if they say they will give you items, np, etc. (I know everyone always says this but its really important)
2) If you suspect anyone of being a scammer report them immediately
3) Change your password often (at least once a month) and don’t make it something obvious like the month, your screen name, or your name. It is best to have a password that contains both letters and numbers.
