[OSM-talk] Still need for spam protection and if yes, what about OSM-based CATPCHA?

[Stefan Keller]

Hi,

Actually, I'd like to hear the opinions of those website admins who
really are affected by spam registrations (see subject).
For those who hate CAPTCHAs please provide alternative solutions.
Whitelists or bayesian filter are not among them.
G* reported that it's delivering 100 million reCAPTCHAs per day  - and
OSM Wiki is one of them for a reason.
Now I'm hoping to get feedback about what you mean to replace it with
a CAPTCHA which helps enhancing the OSM quality.

Yours, Stefan
