The moment your website starts getting a decent amount of traffic, a host of unwelcome spammers join the party. And most of these spammers are automated spam bots.
Well, let’s see. First off, if you don’t moderate comments (i.e. all comments are directly published without any approval) then your posts will be filled with thousands irrelevant content (spam). This will ultimately reduce your SEO score – all thanks to automated spam bots. but, if you started the moderation and daily you need to check a single relevant comment from thousands of irrelevant comments, That’s too much time consuming and reduce the credibility of your website.
If you decide to manually moderate each and every comment, checking them for spam and authenticity, well, you’re going to need a lot of time. This technique has another disadvantage. Apart from requiring significant human effort, your WordPress database keeps getting filled with spam comments. This weighs down your database and makes it slow.
