One of my responsibilities at Search Engine Land and Marketing Land is to monitor the comments on both sites as much as possible. I usually check 2-4 times per day to make sure our community guidelines are being followed and to keep an eye on spam.
We recently switched to Disqus on both sites for our comment system, and while comments have increased since then, so, too, has the amount of spam we get. Ugh.
What’s frustrating about it is that there’s a simple fix that would cut down on probably 80 percent of all the spam we see on both sites: limit the number of comments a new Disqus user can post.
The vast majority of spam we get is from users like this:
Seriously, if you’re leaving more than 5-10 comments on your first day with an account, I bet chances are pretty good that you’re spamming. But 182? 223? 303? On the first day? Wow….
Yes, I’ve blacklisted all of these accounts and yes, I’ve made this suggestion to Disqus via their feedback system. Fingers crossed someone’s listening.
