You have probably noticed there is always at least a dozen or so posts on this forum with someone explaining how they got "hacked". It seems people do not understand how this business of key-loggers and phishing scams work.
Most of the people involved in this business are from China due to the currency exchange from WoW Gold > USD ($1) > ($7) CNY. You're definitely not targeted or anything special if your account does in-fact get raided/stolen from you buy these certain individuals.
These are large company's with hundreds of employees that sift through thousands upon thousands of accounts on a weekly basis. Some of these company's have branches within that actually have people creating their own trojans and phishing scams but a lot of them do not. Most of the people actually creating the trojans and sending out all that phishing scam emails are actually people who are just wanting to make a quick buck.
The people sending out the trojans and phishing scams collect hundreds / thousands of accounts over time and then sell these accounts in bulk mainly to a gold-farming company. They then go through every single account and hope to get as much out of it as they can, they may not get much or they may get a lot.
This EXACT thing takes place with stolen credit card information. Only difference is these guys are pretty much not breaking any laws so they can get away with it.
It's a billion dollar industry. Don't take your account getting stolen or raided as some personal attack on you just to annoy you. This a problem everyone has to deal with so if you don't want to deal with it either keep your PC as safe as you can or just stop playing.
If you still don't get it here is a picture of pretty much what it's like, just imagine 5 guys are all chinese and all the crabs are thousands of stolen WoW accounts.
