Is there a special proxy setting?

Here's the deal. I bought 10 private proxies only sold to me.

I post in the for sale section (no PVA needed).

I used my regular home IP to post about 7 ads in a row and then got soft blocked.

So I switched my IP to one of the private proxies I bought, but it was still soft blocked even though whatismyip.com told me my IP had changed.

My question is this: is there some sort of different setting internally on my hardware or in another software I need to change for craigslist to see the new proxy.

It seems as though even if I change my proxy, craigslist still treats all the different IPs as 1 IP. I can even reboot my DSL modem and get a fresh IP each time and still have the same problem.

I drove to my friends house to test out the private proxies I bought, and it worked on his connection (no softblock)...but back at my home, they are softblocked, so it HAS to be that there is a setting in another program, system preference or SOMETHING I'm missing, if anyone has any help I would be very appreciative.

I use a Mac but tested the proxies in Windows with Firefox as well, even using CCleaner to clear everything. But...still softblocked.

Hope to get some response, thanks!

I'd look into Mac Address Spoofing.

That's really strange gogo.
Until recently craigslist did refresh their block checks every page call.

But anyway: try remove your cookies, then test again
