- The beggar: They constantly ask for your username and password. They try to make you feel sorry.
- Promise maker: They want you to share your account with them so they can "help" you make your account "stronger" and "better". Another case is they claim to be a "hacker" or to be a "very generous person" so they can give you a lot of in-game currencies. They only want your password first. It's indeed a cheap trick to steal your account.
- Account sharer: They want to share their accounts with you and want you to share your account too. They will always ask for your account information FIRST. Sometime, they give away their "accounts" first. However, these "accounts" are not their real accounts. Another cheap trick.
- Impersonator: They pretend to be a game staff member. They will try to make up some craps and then they will ask for your account username and password. Administrators will never ask. Obviously. Moderators are not even supposed to ask. (If they do, report them).
- Trust abuser: They are rare, but when you are their victim, it hurts a lot! They will always try to gain your trust first. Far later, they will make up some craps and some social engineering to try to have access to your account. They might make you feel guilty too. For example, they might say: You aren't generous; I trusted you this whole time, why don't you trust me!?; etc. I know a case where a top Guild fell apart just because of ONE scammer. In that game, there is a trading system. I don't know exactly the details, but the guy managed to scam his whole Guild! The most frustrating part is he became the strongest player in the game. Only few players from the rival Guild managed to beat him. Unfortunately, in that game, the staff members didn't ban him for some reason I don't know...
- Account seller/trader: These one are smartasshole. In some games, selling accounts is very profitable for scammers. Their objective is your money and not your account. They will ask you to pay first. Then, they will give you the account username and password. (Sometime, they might gave you the account information first before you pay. Maybe to tempt you.) You got the account. You are on it, you can play it. MANY DAYS later, you can't access the account. The account got its password changed because, in some games, staff members think the account you just got is scammed or hacked. Result: You lost your money and the account seller got back the account. Maybe you can cancel your payment if you have the chance.
I hesitated. I refused and said "No". He was still insisting and wanted to share so badly. After saying "No" many time, he still insisted. So, I gave up. Just to mess with him, I gave him a newly created account. You know what the moron did next? He BLOCKED me (so he is "offline" for me). He didn't even give away his account information. Then, he automatically went in the account settings and changed the email (so I can't use the password recovery option). I got the notification about the change. After changing the email, he changed the password. Obviously a scammer!
After that, he went back ONLINE because he just found out what I gave him was a new account. He told me that I gave him the wrong account and wanted my real account. To made him pay, I made him taste his own "poison". Somehow, he ended up giving away his REAL account. Result: He lost his account. I still had my account safe. His mistake: He went back online. He could just had stayed offline, but he was too greedy trying getting my account. Personally, I think he deserved punishment because if I was a super gullible fool, I would had lose my account instead. Don't forget it's also hard to punish an online scammer... It's more simple to ignore/avoid the scammer.
