About Astounding Spam Prevention
From the official readme · v1.20Description
Using the most effective features of other spam programs. Astounding Spam Prevention effectively guards against comment spam and registration spam without the use of a Captcha.
This is a fork of the original Stop Spammers Spam Prevention and uses some of the code, but it is greatly simplified so it is not as aggressive and will not prevent a user from logging in. It does not interfere with jetpack and does not know about WooCommerce so there are no conflicts. Unlike Stop Spammers it does not check logins, but only checks registrations and comments.
It also repairs many bugs that I found in the Stop Spammers plugin and has many new methods for detecting spam.
