This is stupid... and even if people actually traded, all of the people willing to trade would have probably already traded. PS buy your alts legit, if you buy off another website chances are that the seller will have full access to the account info and change it withen the month. If you use alt websites chances are that the accounts are stolen from real people.
I used to get alts by browsing the vast interwebs for free alts. Then I would use a program called egg cracker to filter working and not working alts. At one point I had nearly 50 working alts using this technique .
