Blocking Liferea

So I got a little annoyed by the constant downloading of my blog (almost twice per second) by broken versions of the liferea RSS reader. Went ahead and added this to my configuration:

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^Liferea/0.*     [OR]
RewriteCond %{HTTP_USER_AGENT} ^Liferea/1.0-RC[1-3].*
RewriteRule .*$         not-existant [G,L]

This way any version less than 1.0RC4 will stop wasting bandwith.
