Sorry for the late response.
In answer to questions above, some of the things I've tried with the htaccess file is redirecting a specific ip to a specific page, blocking proxy sites and most recently blocking access to a specific folder. For the redirect and the folder access I got 500 Internal Server Error, the proxy blocking simply didn't work.
Not sure why it doesn't work but I end up doing most stuff in php instead. The proxy blocking I've tried in php so far hasn't worked but I haven't really put much time into that.
My site is on shared hosting but from what I can tell the htaccess should work in my site directories. Although all attempts to use htaccess haven't worked or throw a 500 error.
As for the bad bots, I took a shortcut and found a blackhole php script at [perishablepress.com...] with a few minor edits it's working awesome so far, caught bad bots already. I am using it without the htaccess file that is included as it was throwing a 500 error and causing it not to work. I also changed the php version from 4.2 to 5.2 in the php files.
