Logocapcha
Suddenly the idea came: why not use the logos of famous brands of increased recognition as a captcha?
For thematic sites you can use your own set of pictures of a particular subject.
And it will look something like this:
')
Each logo corresponds to a list of matches in different languages (if the site is multilingual), plus the wrong ones (not everyone knows how to spell mercedes).
Of course, this will not save from the crowd of Indians, decisive captchas (if only in the database there is no name for Nike in Hindi :)
Nevertheless, I believe that you can effectively deal with spam only by entrusting this difficult mission to a crowd of users and the “spam” button. And that will just be a fun idea.
