Growing a popular blog is very much a double-edged sword. It’s great when you have lots of new readers leaving lots of new comments, but that also means that your site is more likely to attract all the comment spammers and spambots out there.
Akismet has been the go-to tool for this problem for quite some time, but it is not without its flaws. It “detects” many false positives: comments that are legitimate can oftentimes be flagged as spam and never seen by the blog owner. An alternative to Akismet is GASP and it claims to be more accurate in this regard.
Developed by Andy Bailey, the same guy who made the popular CommentLuv plugin, GASP stands for GrowMap Anti-Spambot Plugin. It works to combat spam from spambots by implementing a very simple feature. There is a checkbox that needs to be ticked before a comment can be posted. The text next to this reads, “Check box to confirm you are NOT a spammer.” Real comments get through and spambots do not.
