I've said this before..........go to WGO click users online (online.php), at the bottom from the dropdown choose to view user agent and check what Artabus has as its UA, it probably doesn't have artabus in the UA.

The following is what shows there Simon:

pool-109-191-73-49.is74.ru
Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461)

What should I use to block it here?

to be safe block the entire string, this way you wont accidentally block legitimate users :)

Simon I feel like a fool asking this...but which one would be the entire string to use?

pool-109-191-73-49.is74.ru

or

Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461)

I don't want to block legitimate users! lol..

the second one, the first is to do with the IP address.

Thanks Simon! lol....I feel like what my Son calls me at times a "Goober"...hahah...:D

VERY few legitimate human users are going to be on MSIE 7 or older.

I block ALL MSIE except 8. Amazing how much that alone cut down on bot registration attempts.

so what do you use to block all MSIE except for 8 Max, htaccess or some other way?

heres an example

Chrome/10.*
Firefox/4.*
so i asume MSIE will work as

MSIE/6.*
MSIE/7.*

and so on

I just have it in like this:

MSIE 1
MSIE 2
MSIE 3
MSIE 4
MSIE 5
MSIE 6
MSIE 7
