How to block all those domain name scrapers

[zeus]

Hello - any one know how i can block all those sites that just use my whois info as content?, robots.txt I think such site ignore those, so htaccess is the only option.

but how do i find those ips to block?

1) view your visitor logs
2) copy and past the IP range into a WHOIS search (i. e., same way they find you).

you can't block bots getting your Whois info, it is scraped from the registrar.

hmm yes i think you are right, totally missed that.

FWIW,
A webmaster is not able to control access requests for another domain, however your own server and control of access requests are unrestricted.

The following are all the same domain (with the exception of the head request) from 2002-2011. Access to all of these requests are certainly controllable, whether through use of IP or UA.

The particular bot, may in fact honor robots.txt (there are many more of these tools in existence and I see new ones (different names)frequently).

Additionally, two of these bot requests offer malformed UA's which offer a simple solution for all requests (not just bots).
