When those renting the domains are paying only a small amount per domain, it can be very time consuming to configure the websites for domain rentals . However those leasing the domains are often free to end the domain lease any time and the domain investor has to reconfigure the domains again.
Some of the domains reconfigured are :
CoRelocations
Beesgames
Iyeg
Onuy
Bodg
Pulse, mushrooms, eggs, vegetables

These domains are also available for rent or sale at a reasonable price.
