On January 2nd, 2011, at 12:23 AM, VendettatheGreat retired from ROBLOX. He did this because he was close to deletion and felt the game was overtaking his life, plus many other small reasons.
VendettatheGreat's reasoning was that he was close to deletion. This is true, considering the fact that he has had over 40 bans in the past (See VendettatheGreat's Ban Record). He also did not state it, but instead implied that he was angry at ROBLOX for consuming his time.
On June 3rd, 2011, which is VendettatheGreat 3 year anniversary, he returned to ROBLOX.
