I have a question regarding proxy sites in general, and answering it will indeed help on whether I'd want to purchase your site or not.
I bought one recently, got hosting for it (at GoDaddy, shared hosting which probably wasn't wise), and then the very next day after it was up, GoDaddy had emailed me about receiving some complaints about spam coming either from me or from the site. Obviously it someone using the site, but my question is what the heck do I do to avoid that situation? I had my hosting deactivated by GoDaddy, who still hasn't responded to my email stating I would take the service off of my site that allowed the user to do what he did and disclose any IP information they desired on the traffic to the site if they didn't have it (and I'm beginning to understand why people hate their customer service because that was a week ago). Do you have to have your own server to run these kinds of sites or what? Can you still get screwed if you do, even with a disclaimer on your site removing liability for illegal activities done while using the site?
I say all this because I would be interested possibly in purchasing your site, since I now have a proxy name with a lot of traffic sitting on a parked page since this mess (still making $3+ a day so I'm not exactly crying over what happened) and would like to put a site on that name and/or redirect it to another proxy site that I'd buy (like yours). I am however unsure of how exactly sites like these can be run without complaints like what I mentioned. I think answering this would also put some others at ease as I think many are afraid to own these kinds of sites for the reason I just laid out. Thanks in advance.
Edit: Well, I just noticed you said you own your own ISP...can you perhaps at least address this concern anyways? Thanks.
