Those name servers were not banned accidentally and they were not banned for anyone else's behavior.
Those name servers were banned because you were DDoS'ing our server with fake calls to hits.php in order to cheat the system and get your proxies listed on the "Popular Proxies" and "Top Proxies" pages of our proxy lists.
You cost me a great deal of time and lost revenue with your careless and rude behavior and you caused this forum to become unavailable to every member here.
The name server ban against INWX.de stands. The bans on all of your proxies stands. The ban on any proxy containing your AdSense ID stands. The firewall rules dropping traffic from all of the IP addresses you were using the DDoS our server stand.
You need to spend a lot more time learning how to behave properly before you're going to be allowed to benefit from our listings again.
