I just noticed that someone has generated hundreds of links to one of our articles through comment spam. I wanted to know if it would be a good idea to delete this article and repost it, thereby changing the article url so the links from the comment spam will lead to a dead page (404). Also, should I also disavow these incoming comment spam links? Thanks.
The answer is no, according to Google. Don't Worry About Spammy Links. And you do not do anything.
John Mueller of Google was asked on Twitter if one should disavow the spammy links that you see from an article going viral. John said "no need" to do that.
