This is how you can identify someone new to the game, or at least the forums.
They take this break every year, and there's really no noticeable change in-game for the week. All the people responsible for maintaining order in the game are still working, it's mostly the devs and folks of that sort that take the time off.
Basically, if you never visited the forums, you wouldn't have noticed anything different.
Having your head burried in the sand isn't a sign that you are a wow or forum vet. The gold farmers scour the forums. It is a billion dollar a year industry and they have teams working to subvert accounts that are as large as the teams Blizzard has to keep them safe.
Nearly every wow fansite you have ever been to is owned by gold farmers (*cough* WoWHead *cough* Allakhazam), do you seriously think they don't scour these and every wow forum daily??!
As I said before ANY opportunity, real or perceived, WILL be exploited by gold farmers. That's just how it works, regardless of how deep you try to bury your head in the sand.
Oh, and while they may take this break every year, they don't announce it publically every year... and to clue you in...prior to the CS changes made THIS year, the majority of hacks to accounts occurred after 8:00 pm PST on Fridays, because prior to this year, there was no one working in CS over the weekends and the hackers could be certain they had the entire weekend to do what they wanted with the account... how's that for a history lesson?
That'd be quite the lesson... if it wasn't factually incorrect in almost every way, or based mostly on supposition and assumption.
They've announced their time off every year, we just didn't have a feature that showed a whenever a blue posted on the forum (again, giving an indication that you really are incredibly new).
Wowhead isn't run by gold farmers, ZAM networks (who own Wowhead, Thotbot, and Alakazam) sold the gold farming company they had previously owned before the purchase of the site. Yes, the advertisements you see running on the site are occasionally (see: rarely, it's usually Blackberry advertisements) gold buying and leveling services, but that is in no way a reflection on the ownership of the site itself. I help run a tech service advice forum, and our AdSense advertisements occasionally run information on electric shavers. Does that mean we're really a front for some kind of electric shaver running cartel?
Hell, my blog based on creative writing occasionally has this one advertisement pop up for "male enhancement" and another for buying firearms without needing a permit, they rarely make any sense in comparison to my content.
Advertisements randomly generated on a site is NOT indicative of anything about the site itself. Typically, most such systems simply take keywords from the content on a site and display advertisements that would be related to said content, and what kind of WoW-related service puts a lot of effort into advertisement? Oh, that's right, gold farmers!
Basically, all your response did was further prove my original statement.
