VGCulture - Steam Market's 200 Item Listing Limit

Official Site: http://store.steampowered.com/

If you have a lot of games on steam, you probably have access to a lot of Steam cards.  And if you're like me, who doesn't really care about badges or steam level, you probably tried to sell your cards away for money to put into your steam wallet.  Apparently, each user is limited to list 200 items per calendar year before being asked to provide extra information so that they continue to sell more items on the Steam Market.  First question, are you a citizen of the country you identified yourself with?  Then it asks typical stuff you usually fill out for paying for the games anyways: Name, Address, City, State, Country, Zip Code; and then *BAM* they hit you with this question: What's your Social Security Number?  Please note that this isn't Valve specifically asking for it, but the IRS requiring any and all users of the Steam client who has reach 200 items listed or has made over $20,000 on the Steam market so that Valve can report their earnings.  This was incredibly baffling to me.  For one, any money that a user makes stays on Steam as credit to use back in the steam market or to purchase games.  Can the IRS really call that an actual "income"?  If someone is making a few hundred and definitely over $20,000 in the Steam Market, then it's fair to track since it is affecting the usage and fluctuation of the economy when so much money is being used.  But a 200 item limit when cards are making 9-15 cents each?  It just seems rather ludicrous to me.  Most importantly, they are asking for an individual's Social Security Number.  That is something an individual shouldn't take lightly as that information in the wrong hands can wreck havoc on their identity, credit, and reputation.  I'm sure Valve would do their best to get your information safely to the IRS without it getting leaked out, but I have to point out that Valve's Steam Forums have been hacked before.  Many large corporations have had their database hacked and it's a common problem nowadays.  Even PC Magazine's forums got hacked just recently.  So as much as I'd like to make a few extra bucks to cover a bit of the impulsive buying I do on Steam, I'm going to have to hold onto a lot of cards until next year unless they decide to do away with the 200 item listing and check only if it goes beyond a certain price range.
