I don't believe I've seen a thread here addressing this yet, so here it goes. This thread may tick off some scammers, but players new to the diablo series need to be sure to know how to protect themselves from in-game trading scams. I'm against both botting & scamming but scamming is what really grinds my gears. My reason? I sort of see botting as feeding off of "nature" at an advanced rate but not hurting people too much directly (it's not helping the economy much obviously), but scammers are just criminals who will actually steal something from you. It doesn't matter that it's digital, you worked hard for that item/gold and it's potentially worth a few bucks in cash, or even some nifty blizz bucks. Most D2 players will know what i'm talking about right off the bat, but for those new to the series, a scam can easily catch you off-guard. I won't go into detail about how they work, I will just help to ensure that you don't fall victim to one.
1. When you have the trading screen open and you've just finished typing in how much gold you'd like to trade, wait at least 4-5 seconds until you click the "Trade" button.
2. When trading an item, be sure to RIGHT CLICK the item in your inventory that you wish to trade, that will instantly transfer it to the trade screen. If you left click and drag the item, try your best to get out of the habit of doing that. This may sound silly, but be suspicious if the player keeps standing right on "top" of you when attempting to trade, even after you move away.
3. Try your best to get the person you're trading with to send you a whisper at least once, If they refuse and only talk in party chat be suspicious, they may be a known scammer. Blizz has been known to "mute" accounts that are constantly flagged for scamming , they will not be able to whisper you, but they can talk in party chat (and trade chat too, though I may be wrong).
Remember, If someone does try to scam you please be sure to report them so that they are flagged ASAP. Also, the majority of players wanting to trade are legitimate and decent people, don't let this stuff discourage you from trading!
