Wiki's Spam Filter and External Links

[DarkClaymore]

Not sure it's supposed to go here but...

Is there any way to get around the spam filter or request to allow a certain link?
I was editing my wiki page but I can't link to some of the games I played because apparently the site is on the "blacklist" for some odd reason.

This is the site: http://nisamerica.com/forum/index.php if it can somehow help you answer.
