I guess it was my turn to be hammered with registration emails recently. I received few hundreds undeliverable emails for past couple of weeks comming from russian and chinese spam bots. Turning off email validation is not an option for me because the site in question is a review community and I need to be sure that the persons behind the reviews are real.
I didn't want complicated solution involving more software installed on the servers so I decided take Google's reCAPTCHA API for a spin :)
And here is the result:
More details: http://www.zaaron/gt/
Description: The reCAPTCHA plugin integrates Google's reCAPTCHA API to GLinks to prevent spam. What's different about reCAPTCHA is that they use the verification words to correct OCR mistakes in scanned books.
In their words: "About 200 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that's not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into "reading" books."
The plugin currently supports the following user actions (all configurable):
- User Sign Up
- User Login
- Add Link
- Modify Link
- Rate Link
- Add Review
- Modify Review
No images are stored on the server
No GD or ImageMagick needed. =)
