The 20-year-old R&B star, who posted under the username MechanicalDummy, reportedly wrote a final message to supporters yesterday before pulling the plug on his microblog.
Brown declared: "I WANNA THANK MY FANS FOR ALL THE SUPPORT. I LOVE YALL. GOODBYE!!!!!!!!!!!!"
At the weekend, the singer had used Twitter to complain about record stores refusing to stock his new album Graffiti in the wake of his conviction for assaulting ex-girlfriend Rihanna.
In a further update, he had said: "JUST WAS AT WALMART IN wallingford CT,844 north colony.. the didnt even have my album in the back... not on shelves, saw for myself...we talked to the managers and the didnt even know anything. wow!!! (sic)"
According to E! News, the remarks prompted Walmart to release a statement, which read: "We are surprised at the comments online. All Walmart stores nationwide have carried the CD since its release, including the Wallingford store mentioned in the post. This store actually sold through its initial shipment over the weekend. The majority of our stores today are showing they do have copies available."
Brown expressed remorse over his treatment of Rihanna in a recent US TV interview.
