Captcha needs Javascript to work, not Tor friendly

Post by Guest » Thu Dec 01, 2016 6:19 am

The captcha needs Javascript to work, so this forum isn't exactly Tor friendly. I know that captcha can be done without Javascript, for example What Is My IP manages to do captcha without Javascript using reCAPTCHA which generates a code that has to be copied, pasted into a field and submitted.


Other options in case you are not too comfortable with embedding a Google service into your forums:

Honeypot captcha hidden from users via CSS:

ASP.NET based captcha:

https://www.codeproject.com/kb/custom-controls/captchacontrol.aspx

The author of that StackOverflow post also mentioned a few text based options:
ASCII text captcha: \/\/(_)\/\/
math puzzles: what is 7 minus 3 times 2?
trivia questions: what tastes better, a toad or a popsicle?
