Ask HN: Favorite methods to block spam in your apps?
Lately, http:&#x2F;&#x2F;www.theprobono.org&#x2F; has been absolutely slammed with spam project postings.  They tend to consist of random characters for the username, random real-world locations, and typical spammy descriptions.<p>I just pushed a sanity check for the time between when the form is displayed and submitted, ensuring a reasonable amount for a human to fill it out.  Beyond CAPTCHA and honeypots, any other ideas?<p>I&#x27;ve also been looking for a possible 3rd party service that could look at the project description and give a &quot;likelihood of spam&quot;.  Any thoughts?<p>Thanks!
