Anonymous Proxies?

I am an advertiser on a certain well-known site and I've been having issues with keeping my ads live. Every time I try to post an ad, it gets deleted before it even goes live! I remember posting an ad and it got deleted by staff literally less than 4 minutes after first submitting the ad. I can't even post anymore because my ads either get ghosted and then deleted or they just plain get taken down before they even have a chance.

I've tried 2 VPN's and a few free anonymous proxy servers. I've even tried using different emails, but nothing gives. I tried one VPN and I discovered that most of their IP addresses were on IP blacklists :-O

Is there an anonymous proxy server or VPN that actually works with this certain site? I'm tired of constantly posting ads and getting them deleted. I don't post anything inappropriate nor do I spam listings. What do I do ath this point? I am losing business because my ads can't stay up. :-(

Are you linking to a specific URL or domain that they may have blacklisted in their system? If that's the case, it doesn't matter how many IPs or emails you burn through...

I never post links in my ads, ever. I believe it's either my IP address or the VPN's IP addresses that are the culprit. I won't name the VPN I use out of respect for this website. I will say that I found out that most of their IP addresses are on blacklists and that I didn't find this out until a few hours before I uninstalled it.
