2009 player badge glitch

The 2009 player badge glitch was a glitch on Roblox that allowed users to create as many player badges as they wanted for their experiences from September 2009 until sometime in 2011, when Roblox fixed the bug. This glitch was performed by clicking the buy button on the Purchase Badge page, clicking back on the user's browser, then buying another player badge. This could generate infinite badges for the price of one badge, 100 Robux.

History
It is believed the glitch was first discovered by, who used it to purchase 1,200 badges for their experience Ultimate Space Adventure 2.3. The knowledge of this glitch soon spread amongst users on the forums.

Despite popular belief, badges and experiences that used this bug were not deleted by Roblox after the bug was fixed. For example, Rock And Roll Tycoon by has 25 badges created from this glitch that remain obtainable. A more extreme example is Badgeland by, which has 435 obtainable badges created using the glitch. However, many experiences that used the glitch were closed or had their badges become inactive over time due to the creator's Builders Club subscription expiring.
