From time to time I got a few spam comments at my blog. Such comments contain multiple links inside to increase somebody’s sites ratings in the search engines results. This job is made by software bots obviously.
I use Disqus comment system plugin for users comments here at shinephp.com. This plugin duplicates any comment sent to Disqus in your WordPress blog database. This is good thing in case you decide to change comments system in the future. But I still got some comments at my WordPress database only without pair at Disqus. So I have a conclusion that there is a way to send comments to WordPress blog even without opening its post in the browser. Cases when the same comment text inserted into multiple posts at the same time just confirmed my thoughts.
While there were 2-3 spam comments a day I did not take much attention to that. But recent days spam comments quant was drammatically increased to about 30 a day. So I had to search a way to stop this annoying thing.
Good news! It seems I found the right decision.
