Well, because this is a free hosted site I see ads, but that's about it.
I took some of that info off of the portal because of the spammer problem (phishing). You can still view that information on the Forum Index page.

I just clicked on Who's Online and found a dandy example of what I'm talking about:
Guest (66.249.71.180) 12:36:49 AM Posting in Politifact's Strange Ruling.
That IP is Google, and Google can't post. What's happening here is that Google is being used to see the Last Post statistic which displays the last thread posted in and using that thread data, a hacker is using Google to attempt to post.
In the past, hackers have used data from "latest member" to hack into that account to gain access (or to collect data) as well as used admin accounts (always Member 1) to change passwords. Attempts of this nature are ongoing on this site and taking that info off the portal makes things harder for 'em to hack into the system.
