I have used the services provided by Sulake (Habbo.com) for over 10 years. I occasionally check up on the prices of "rares" I've purchased to check my virtual ROI. I recently logged in and noticed, at least, 3 of the "rares" I was selling had vanished completely from my account. These items totalled approximately 22 USD. I compiled a series of detailed screenshots I had taken over the years of the negligence and incompetence of Habbo staff and presented them to my attorney, who advised me that several were evident breaches of Habbo's end-user license agreement.
I would strongly discourage anyone from using any service provided by Sulake or its subsidiaries.
