Help needed with htaccess

Im running a 3.8 forum with vbulletin blogs on it

Seems the toe rags from Russia China etc have now decided to latch on and bleed content through the blogs feeds

Vbseo rewrites blogs.php to /blogs/ and the feeds to /blogs/feeds/
When the feeds are only blog_external.php

I tried deny access to blog_external.php, with no luck
I dont use the blogs feeds, so stopping all access aint going to cause any problems

Any ideas on how to add a block via htaccess. Since there aint no folder called blogs, so I cant shove the block in that

you can set anything (even virtual) to fail

Code:

RewriteRule ^/blogs/feeds/$ - [F]

Cheers for that Brian, your a star
