I have set up a little program so that you can download the current working version of a few of my plugins. These may or may not be the same as the ones in the WordPress Repository. I do my testing here, so if the site is not crashing it is probably OK to download the plugins for your sites.
You can read here how to manually install a WordPress plugin.
If I specifically mention that there is some bug fix in the beta version then it can be assumed that I have yet to upload the plugin.
Please uninstall and delete the bb-fix-stop-spam plugin. I have included its functionality in the 4.1 Beta test of stop-spammer-registrations-plugin. Download and install the stop-spammer-registrations-plugin and test that.
