I purchased and immediately started using Human Presence back in February 2022 and loaded it on about 30 sites that are mine and my clients.

I simply do not trust the plugin for subscriber and/or contact forms, plain and simple.

There's no way to verify that what the plugin considers non-human submissions are really non-human submissions. You cannot test out the plugin by submitting your own form(s), because the standard reply from the developers is that the plugin must have detected spam-like activity.

It's almost like you're being gaslighted. "If you don't see anything happening, then that's how you know it's working."

Not only did it almost cost me a client, that client is a lawyer and was threatening to sue me because of the 300 form submissions that were sent through her contact form that was "protected" by Human Presence only 20 submissions were seen as valid and allowed through. It was only after she talked to a few people who told her they tried to submit her form that she let me know that there was a problem and accused me of potentially cost her money from potential clients.

After avoiding litigation and not losing that client's business, I went through all my sites and all my clients' sites where I'd installed and activated Human Presence and saw the same pattern of super high rejections and very few submissions being let through. Human Presence does not store those submissions for you to go through and decide whether to whitelist or delete them. They exist nowhere, because the person trying to submit the form isn't actually allowed to submit the form. They get an error message and nothing goes through, but Human Presence registers their attempt as suspicious.

Again, I simply do not trust the plugin when it comes to subscriber and/or contact form submissions.

I gave it three tacos, because I intend to only use it for comment forms.

Many of my clients and I are not concerned with whether people can leave comments. Also, after removing the plugin from a few client sites, they all [within a day] informed me that they started receiving a lot of comment spam. When I put the plugin back on their sites and limited it to only protecting the comments form the comment spam stopped within hours.

So... The plugin is not totally useless, but as I mentioned before I do not trust it with my or my clients' subscriber and/or contact forms and will only use it for the comments forms going forward.
