Many of the comment spammers look for "dofollow" links by checking a page to see if it contains "nofollow". I'm thinking if a page has a nofollow link somewhere on the page, many of the comment spammers will think the page comments are nofollow....I'm pretty sure most spammers don't check every link, but rather just search a page for "nofollow".

Include a CPA or email opt-in on the page that is targeted to the demographics of the video.

Then drive traffic to the page, capitalizing on the video's popularity.

If that's the way comment spamming software works seems like it's a very valid idea. Would this work for links in the sidebar to high authority sites? Worth a try.

However, the theme on the sites I was just thinking of adding that on is built to not allow comments. I'll try it on the next batch of sites I build/buy with a different theme. But that could be awhile. Things are going very slow.

Hey Sandra....

It's really the only way for a program to check for nofollow, since there isn't a "follow" tag.

In theory, the program could try to isolate the nofollow to just comment tags, but I doubt 99% of them are than sophisticated.

What I'd do is put at least one nofollow link in the footer of each page. Since it's a good idea to use nofollow for TOS and privacy pages, this could kill two birds with one stone.
