Comment Spam Control

Hi All,

I am just setting up my first MU site and I have been going through all the forums so that I can pick all your brains.

You guys are a bunch of geniuses!

But this question has to do with Comment Spam (as mentioned in the title)

I have been looking for a site wide comment spam control and everything I find is dated.

I have the Farms Comment Spam Pack but the last comment I see on it is from about a year ago and I was wondering if it still works with 2.7?

Also I read a couple of long post about how Andrew made a MU version of SK2 but had to pull it because DD said it wasn't GPL.

It is GPL now:

And I was wondering if the SK2 WPMU would be re-released?
