Blocking Baidu & Yandex

Hi Jeff

I am perplexed as to why I can’t keep Baidu and Yandex out of my site. Perhaps you can suggest a different line of attack?
1.)WordPress runs in the top level at gt-rider.com
– Block Bad Bots is installed and both Baidu and Yandex removed from the whitelist. A couple of alerts on naughty bots have been received since I installed it a couple of days ago.

2.) Xenforo Forums are in a subdirectory /se-asia-motorcycling/

3.) I’ve added the Baidu crawler range to the WHM Blacklist – 180.76.15.1-180.76.15.255. Those are the only Baidu IP’s that are appearing.

4.) I’ve added blocking code into the top of .htaccess files (root and forum);
# block baidu + yandex bots
<IfModule mod_rewrite.c>
RewriteCond %{HTTP_USER_AGENT} baidu [NC]
RewriteCond %{HTTP_USER_AGENT} yandex [NC]
RewriteRule .* – [F,L]
</IfModule>

HOWEVER: Right now, there are 15 or so Baidu bots all over the place, and several Yandex bots – both having ignored the instruction to not index Forum Members…

I’m perplexed as to how they get past the Server blacklist, then the .htaccess files. Do you have any thoughts on that?

Kind regards
Ben
