The Wordfence explanation is from their FAQ, and goes:
Plugin has been removed from WordPress.org
This means that a plugin is no longer available to install from WordPress.org. Plugins can be removed from WordPress.org for a variety of reasons, including that the author intentionally stopped its development or converted it to a “paid only” plugin. A plugin can also be removed if it violates WordPress.orgs terms of service or if it contains vulnerabilities. If it contains vulnerabilities, it may be restored to the repository within a few days. As a general recommendation, unless you are familiar with the code in the plugin, we suggest that plugins that have been removed from the WordPress.org repository are removed from your site.
Wait and see?
Wordfence automatically removed the plugin from one of my sites. I am guessing there is a serious security flaw. I really liked the plugin for its simplicity and the ability to work around that size limitation that many WordPress installations impose.
Yes, what happened?
