Criticism
On an unknown date, Roblox gave a few original owners who kept their Dark Assassin a refund of the original price (12 Robux). The owners were angry and posted their reaction throughout the forums. One example is REDSKULLBASHER, who had the Serial #17 Dark Assassin but was refunded. Today, Merely owns Serial #17.
