You can see the reCaptcha at work on some of the RSVPMaker.com sample posts. Not sure offhand what’s interfering with it working on your site.
RSVPMaker registrations are stored in a custom table, which will be called wp_rsvpmaker if you haven’t changed the wp_ prefix on your site. You can query by post ID if a particular event got lots of spam entries.
Just a sad fact that spam robots will attack anything that looks like a form. Personally, if the spam level is tolerable, I usually keep it simple because I want to make it easy for people to register — but I understand how fast it can get out of control. ReCaptcha is one of the less intrusive methods.
Thanks for the quick response David, and for the directions on where to clean these out of the database. Regarding the missing captcha I’m guessing I have a theme conflict, it’s a really old theme that is overdue for replacement. It looks like you update the plugin very regularly and I appreciate your intention to keep it simple to use. Perhaps the wish list for future updates could include Akismet integration and a spam honeypot? I prefer the behind-the-scenes filtering over the often frustrating captcha puzzles. I run Gravityforms on 50 or so sites with these two features enabled and I’ve literally never had a spam entry get through. Unfortunately a bot has already sent a couple hundred submissions to this form today. I removed the notification email to spare the site owner any more viagra ads but that’s not a long-term solution.
