Validator user-agent ?

Is this one in your .htaccess file?

Failing that I'll try some log action tonight.

Thanks, but nope, thats not included

Theres over a 100 blocked so removing them one by one would take forever.
All blocked have been bad at least 3 times, sucking bandwidth, email addresses or leeching stuff

W3C_Validator/1.432.2.5 - HTML
and
Jigsaw/2.2.5 W3C_CSS_Validator_JFouffa/2.0 - CSS

According to my logs.

Makes sense, but why on Earth would you have those blocked Busy? Surely you're not that daft?!

None of those keywords are blocked

here is my list (smaller one that is blocking as well)

Am sure they not in that list, only other sites block are by IP and none were even close to your orginal link Jeeves

Ok, stupid question coming up: If you take these rules out of Apache, validation works?

If so, what happens if you remove only the ip's (as we know the user agents are ok)?

To be honest I haven't tried removing them as I was hoping it would be an easy fix instead of going through each one. Even doing that it may serve from cache (even with f5) so could miss a line.

IP's are:

Stupid me, the IP's aren't at fault as they would just be denied access, it has to be the user agent as it's being kicked to no-one-home.com (or whoever I point I to)
