Well, it passes the "Scunthorpe" test for that word at least.

Oddly, it flags "sex" as profanity while finding "rape" not profanity. "sexual" is fine though. I found a false positive -- "cornhole" -- which is a sport most popular in the Midwest:

It also handles the "space in a swear word issue".

Cool, I actually am on a project that needs exactly this. However, I find the pricing for profanity confusing. Per simultaneous requests is a bit strange and makes it hard to determine what we need. I think you should consider doing it by total volume, with some sort of automatic rate limiting if you must.

Upper Dicker, Lower Dicker and Cocking all get through as well.

Titty Hill - http://en.wikipedia.org/wiki/Titty_Hill - does unfortunately trigger the filter.

Hey Everyone,

I'm Jon (CTO) of WebPurify. I wanted to answer some of your questions.

1) There will be false positives and negatives with any profanity filter, we just try our best to minimize these. Our filter's algorithm is based on several years of feedback from our customers and you have the options of adding words to your custom allow/reject lists.

2) Most of the alternative image and video moderation services use crowdsourcing, which we have found to be generally inaccurate, not to mention there are security issues.

We have dedicated teams.

3) Simultaneous connections means the number of open connections you can have to our service at any one time. We chose this pricing model because it takes far more processing time to filter 100,000 characters than it does to filter 10 characters.

So basically, the longer the text you filter, the fewer requests you can make in a given period of time.

4) Our Video Moderation API will be publicly available in the next few months, until then contact sales@webpurify.com if you would like to discuss a custom project.

As always our Support Team (support@webpurify.com) is available to answer any questions you may have.

Thanks!

Scrotum is marked as profane too, when I am not sure it should be.
