Komento Spam

I keep getting 5 comments per day on various topics all which seems like spam. I have integrated with Cleantalk, but I was wondering if there is a way to turn off links in comments so no one can post them. The challenge I keep getting is it seems like one person is posting a link over and over and over again to the same website, and the content he or she is posting has nothing to do with the article it self. It seems like the person is targeting different articles, and it looks like the links are going to bad websites.

Is there a way to prevent links from being in Komento so I do not get as much spam? Or is cleantalk my best option?
