Block Feedreader.com on vbulletin 4.

[synseal]

My site's content is duplicated by FeedReader and indexed at Google. This forms some sort of content duplication to me, and I believe it does harm to my forum. I have had instances where we was at position 1 on google to find feedreader taken its place and my index gone!

Does anyone know how to block feedreader.com from iframing my site or is their a modification that will block this type of thing.

For instance

http://browse.feedreader.com/c/TechKings/417464980
http://browse.feedreader.com/c/TechKings/411661658
http://browse.feedreader.com/c/TechKings/505121322

I have so far tried blocking their ip addresses to no avail.

deny from 67.210.247.197
deny from 67.210.247.247
deny from 67.210.247.193
deny from 67.210.247.196


I also tried this in my httpd.conf but it hasn't worked.

RewriteBase /
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} bo.lt/ua [OR]
RewriteCond %{HTTP_USER_AGENT} feedreader.com
RewriteRule . - [F,L]

Any help greatly appreciated.
