Comment spammers are getting trickier.
Today I had a comment which I thought was from a regular reader of ProBlogger. It had their name, their email, their URL but the comment was a link to a parked domain with just ads on it and the IP address was not the person who the comment claimed to be from.
Spammers are harvesting genuine comment leaver’s details and using them to leave comment spam with them in an attempt to get past bloggers.
So rather than just scanning comments and allowing anything from familiar names you might want to take a closer look at what the comments are actually saying.
