How to Delete Spam Comments From WordPress

There are two certainties in life, paying taxes and Spam comments on your WordPress blog. The good news is that by using WordPress as your blogging platform you have some incredible tools already built in to prevent Spam comments from ever being seen by your readers.

All current supported versions of WordPress come bundled with a great plug-in called Akismet Anti-Spam. This plug-in has been around since 2005 and it blocks over seven million spam comments per hour! The stats are crazy!

Askimet Anti-Spam does look at the comments marked as spam to learn and improve the way it identifies comments. I haven’t seen any adverse affect to the plugin by removing all of my spam comments on a regular basis.

I’ve been asked ‘Why is my site getting spam comments?’ in the past. The answer to this lies firmly in the ‘black hat’ SEO world. People will create bots that go off and post spam comments on blogs to improve a websites search engine page ranking. If a lot of links point to a web page, search engines think that that particular page is important and will show it higher in the results pages. Blackhat practices like this are largely redundant.

Bulk Remove SPAM Comments 

Fortunately it’s fairly straight forward. To remove those un-wanted comments all at once we’re going to be writing a query and executing it using your MYSQL database. To achieve this you need to make sure you have access to your database. Make sure to backup your database before running any statements. You don’t want the headache of not having a decent MYSQL database backup if you accidentally delete everything! If you aren’t sure how to take a MYSQL database backup check out this article.
