Anyone using a script to import bad host files for blocking

I’m thinking of a semi automatic approach to importing a text file of badhosts/etc into the mk firewall.
is anyone currently doinging something simlar?

this script uses a txt file of bad IP addresses that’s hosted elsewhere, maybe you can get some ideas here http://wiki.mikrotik.com/wiki/Conficker-Virus-Blocking

thanks normis, that’s a great starting point for me.

interested to hear if anyone else uses different approaches also.
