ReCapcha doesn't save?

Question

CAPTCHA

What to do if reCapcha doesn't work? Spam breaks into the feedback form ~10 times a day, I completely ignore the captcha. Even a person will not read it the first time, but here ...
Has anyone encountered a problem?

Answer 1

Usually a stupid question with the text "how much is one plus one" killed all the Indians and Chinese from me.

Answer 2

maybe the Chinese drive in for 0.01 dollars

Answer 3

Try to display captcha in Russian (if the site is for CIS). Hindus and Chinese will no longer be able to enter captcha for half a cent, and I have not seen solving Russian captcha, and if it exists, it is clearly more expensive.

Answer 4

Make your own logic captcha. And change its algorithm (well, or variable names, order) once a month.

Answer 5

if the site is on asp.net, then you can try the NoBot component from AjaxToolkit,
if not, then you can use one of the mechanisms that is used there: if the user clicked on the “send” button faster than N seconds, then the user is a bot, timing N can also save from the Indians, since they do not print something on the form in the case, but stupidly read the captcha and fit in, say, 4 seconds, and a normal user, having typed a message, fits, for example, in 10 seconds.

Answer 6

There is also such a thing www.stopforumspam.com/ and the implementation of checks for forum engines.

Answer 7

Read my comment in the last question. Captcha doesn't always help.

Answer 8

It is not trite, but the ban on registration on my mail forum *@yahoo.com and *@gmail.com forever repelled bots.

Answer 9

perhaps the hole is not in the captcha, but somewhere in the code there
was a good article “how they broke the captcha in Bitrix.”
