CUNY Academic Commons

I think we should skip the requirement if the comment author is logged in.

We will also have to do a review of existing Commons plugins to make sure that whatever solution we go with doesn't conflict with CAPTCHAs generated elsewhere.

Tahir, could I ask you to do a review here? The goal is to find an existing plugin - whether already installed on the Commons or not - that could be network activated across the Commons, to force a CAPTCHA for all comments. Ideally, the plugin would have an option that allows the CAPTCHA to be disabled for logged-in users; if so, we can hardcode a filter into the Commons codebase that'll turn this option on all the time.
