Over the years, I have tried so many things to limit comment spam – yeah sure; you can go and install Akismet, or AntiSpamBee – they are great products and seem to do a great job, if you don’t mind reviewing your spam messages from time to time to rescue real comments.
I recently gave up on all spam plugins – I have effectively turned all my anti-spam products off and moved to something a little more simple! Since installing this plug-in, I have gone from ridiculous amounts of spam to zero so far (I just don’t believe it, surely something must be broken!? I assure you everything looks OK to me so far). Do yourself a favour and check out this plug in! (here’s the link to the wordpress.org page) So far, it seems to work OK with WordPress 4.5.3.
My spam content is now zero, and real comments come through – It does seem to be working (for now). It will be interesting to see if someone decides to target my site now – We shall see.
[UPDATE June 2017] – Still no spam since August 2013! This plugin is awesome!!
