[tor-relays] my IP got blocked

Hi everyone, I`ve got an issue with my local IP address. I am running a relay about 1 year and since 3 or 4 weeks I can`t reach some websites like: ebay or ikea. All I get is this message: * * *Access Denied* You don`t have permission to access "Http://www.ebay.com/" on this server. Reference # ____looong number______ I think I am on some blacklists. After I change my IP address all worked fine for only 2 days. Can I do something about this? Thank you for your help! Kind regards Kalle
