ALL those whois sites are really getting on my nerves, some even copy your full html from you frontpage. My site has been in trouble for years, slowly I think its be cause of all those whois sites, be cause they have sometimes a full copy of my site text, sometimes 200-500 words.
How can I block those or is there a list of most of those sites ips which could be blocked.
You can block them the same way you block all unwanted robots. As Alikiris says, until they decide to remove it, it will stay there. Blocking only the IP of the site won't help much, they likely are scraping each other for the data, and other bots are collecting stuff to sell to them. If you don't plan to spend a few hours a day checking your access logs it becomes a wasted effort.
