Just installed Growmap Anti Spambot Plugin (G.A.S.P).
This blog has been plagued by spambot comments, and I wanted to try something other than Akismet. G.A.S.P. works by adding to the comment form a simple checkbox which must be checked before the comment is accepted. The default prompt for the checkbox is
Confirm you are NOT a spammer.
UPDATE @ 3/21/2016: As you can see in the comments, I stopped using G.A.S.P. and started using Shield, formerly WordPress Simple Firewall, in October, 2013. It’s my standard, go-to plugin for blog sites. As of this writing, it has a 4.9 rating (out of 5) based on 356 reviews.
The nSiteful Tech Blog (the official blog of nSiteful Web Builders, Inc. since January of 2013) is where I (Jeff Cohan) and (occasionally) associates will be posting articles of potential interest to like-minded techies, nSiteful clients who are playing active roles in the maintenance of their own Web sites and blogs, and pretty much anyone interested in how Web strategies and tools can help them reach their goals.
