WordPress MU

most of spam and splog i receive is come from isreal ?!!
is any way to block registeration and comments from specific country

yes there is a plugin similar to what you like, http://wpmudevorg.wordpress.com/project/Limit-Country-Signups

this will limit only one country to singup i need to prevent only one country .. singup and comment

Modify it then.

:-)
thats why I gave you the link, I mean come on, if the plugin checks if you are coming from a certain country and then if you are coming from the right country, allows you to sign up, you just negate that check and its done :-)
meaning all countries except the one are allowed to sign up...

doesn't strike me as too hard to manage...

or ban them from the server level.

apf -d

now i wanna to create option page under wpmu admin menu .. where to begin

I just load up a deny at the htaccess level. simpler.

We do ours at the firewall. The traffic never gets to the webservers. Decreases load on the boxes which is a plus.

What's with all of the sig links all of the sudden?
