Elitegunslinger writes "Microsoft offered their club.live.com service as a means of playing games to gain tickets and earn prizes. However during June there was an exponential growth in prize orders received. Microsoft's response to these orders was to cancel them.
Many of the orders had been made through "botting" and automated programs. However prior to September 12th, 2007 the "Live Search REWARDS PROGRAM Terms and Conditions" didn't state that the "bots" were not allowed.
Because Microsoft never stated prior in their terms and conditions it was indeed just to use automated programs. In the confusion of players who "botted" and didn't "bot" many of the legitimate tickets made had been deleted along with prizes that should have been covered by the original terms of service.
Many of the players had made multiple accounts to avoid the ticket caps on club.live.com in order to get more prizes and in turn wasted more time. The terms of service once again never stated that you couldn't have more than one account to avoid ticket caps until September 12th, 2007.
I am unsure of the exact date however according to my sources there was a change in rewards from any amount to a limited one hardware and one software prize per household on July 18th. Which didn't cover the month of June as stated before.
False advertising may be at play here because Microsoft gained unique searches which boosted their live.search.com scores. In turn many children and adults wasted their time playing games and had never been rewarded by Microsoft. This could range from tens to hundreds of thousands of players to even millions."
