Linden Lab Official:Some landowners seem to be charging their own tier for land in US$ through Paypal or some other system -- what's going on?

Residents buying or renting parcels on Private Regions and Estates are subject to the covenant that governs the land they're renting. If you rent land that's in a Private Region, you're not paying Linden Lab -- you're paying the Estate owner. The way in which the Estate owner sets up payments and what they charge is entirely up to them. Understand that by renting from another Resident, you run the risk that this Resident may decide to leave Second Life, without refunding anything you may have paid them. Linden Lab is not party to any agreement the two of you may have, however, if you wish to pursue this matter outside of Second Life, please know that Linden Lab cooperates fully with any real-world justice officials or law enforcement agencies credentialed with appropriate civil or criminal jurisdiction.
