No thanks. I don't think so. Using a proxy filter as you suggest would require setting up either a proxy inside my network, or installing a software proxy on my computer(s). An unneeded expense in time, CPU cycles (as I donate all my spare cycles to Stanford University's
Folding At Home), and hardware.
As far as ad-filtering software goes (which is what I believe you were actually thinking of), I get at least as fine a control filtering domains by editing my hosts file than any filtering software can offer, without any surprises. And I don't need any unnecessary programs on any of my systems. Installing unneeded software is the cause of 90% of computer problems (caused either by shoddy programming, introducing unneeded complexity to the system, or a combination of the two), and though I appreciate the income I get from fixing other people's clustermucks, I don't get the same satisfaction (or compensation) from cleaning carp out my own computer.
No, I think that as long as you rely on advertising domains like DoubleClick and their ilk to collect your data, you'll just have to do without mine.
Sorry, I don't mean this to sound like a rant, I respect your right to make money (in the past I've made a point of following your links, and NOT going to the retailers directly), and I also respect your right to decide how users access your website, but
I decide what goes on my machines.
You might want to consider that I'm probably not the only one that feels this way. Are you sure you want to loose your data from the technically savvy? I mean we may not buy loads of the high margin items (as far as pre-built computer systems goes), but we tend to buy a good deal of new hardware and other gadgets, and probably are a pretty good barometer of what is, and is not, going to be adopted by the mainstream. Who do you think they ask what to buy?
