Yep; better than outright blocking or hosts file manglement is to
redirect to a blank page internally.
This way, the ads get blocked, and the user experience is much smoother.
The only problem you'll hit is if the site is written to validate the
ads running on the client (this is where adware/spyware typically
happens, BTW)

This problem has come up with eBay. I block doubleclick.net on all
firewalls. Starting April 1, users that had required access to eBay
could no longer see anything. Turns out eBay and DoubleClick.net started
working together on April 1. Not a funny joke at all. I have had to
allow ebay.doubleclick.net for things to work.

Thought I'd pass this on to everyone using SurfControl. Our finance
office was reporting problems logging into the Wellsfargo CEO portal.
(www.wellsfargo.com->Commercial->CEO Portal Sign On)
At first I thought it was a problem with RainConnect splitting the
traffic between different ISPs. So, I created a Dynamic NAT Rule to
direct it through one ISP only (I've had to do this with other sites).
That didn't help.
I then started playing around with SurfControl Rules to see if that had
an effect. I found that if I bypassed all the rules in SurfControl, it
worked fine. So, I started looking closer at which rule it was causing
problems.
It turns out that if you block the Advertising & Popups category, it
will block sites like Wellsfargo's CEO portal! Not blocking the actual
site, but apparently the images contained therein are necessary for the
portal to work. I'm starting to suspect that might also be the cause of
other sites running quite sluggish lately.
Is it a mass conspiracy? If you block their webtracking software, they
won't allow pages to load properly? Ooooh, the deviousness!
