Senuke Proxy vs. Changing ISP IP address

If I am running Senuke for 3 sites, do I need to purchase a proxy service and get some private proxies?

Or can I just change IP addresses in my router? I have created a script using AutoIT that will pop open a browser, login to my router, navigate to the proper area and select the operation to pull a new IP. I added the script to a toolbox and it seems work fine (but a little slow to use after each and every operation).

TIA.

I would suggest using your own ISP IP for senuke or even use a private VPN service. I have found even good private proxy services to decrease the success rate by a lot. I tend to change my IP once every 1-2 months, and blast constantly throughout that. Haven't come accross any real problems with getting banned from too many sites yet.

What about getting banned from your VPS by spamhaus complaints etc?

Thanks everyone for the responses. So far, so good.
