Yep it is about scamming. I wanna give you some information about how to save your poor account from being emptied :P
Let's start...
1) Try using a difficult password. Avoid PWs that have your birthdate in them, or PWs which contain a part of your username. Never use an obvious password like : qwerty ,12345, 11111 or noob123 etc
2) When playing at a Cyber Cafe, Net cafe or whatever, be sure that you are alone when you are typing your pass. Many eyes can catch a glimpse of your pass and scam you. Protect the keyboard with your arms if possible.
3) No server owner, no server employee will ever , EVER ask your password. Simply because they can find it themselves via the db.
4) GMs and Admins do not care about your email, and email password and be sure that you don't give it to anybody.
5)When you are added in MsN by unknown players, which send you pictures, or rar files or whatever, right away, block the file delivery and block/delete the contact right away.
6)Never drop a weapon when a party is set at "loot by turn". It may cause your wep or armor or anything being picked by the other party members.
7) When you trade money for an enchanted wep, check what is given to you before trade, because from the icon you may be tricked.

-There are many emails like dhx_l2goldadmin@l2gold.org, or admin@l2gold.com, or dhxadmin@l2gold.org or admingm@l2gold.org etc. T-H-E-Y A-R-E F-A-K-E. They will trick you and scam you, they may say that you can become gm etc. DO NOT BELIEVE THEM!
Hope I helped ;)
