You don't necessarily have to have the Verizon service to post successfully on CL at that volume. There are other options. You could get a dialup line in your home. Most of the time, disconnecting and reconnecting will change your IP address. Also, there are other wireless carriers outside of Verizon. Lastly, if you have a highspeed connection with a dynamic ip, then you can restart your router to get a new IP everytime you do so.

The good news is that all of this can be done with macro software like Automate or macroexpress.
