Hi Reimar,
Sorry, I was not being clear. I was trying to explain how effective
Textchas were. At the risk of getting off-topic, I'll explain what I've
been doing in the hope that it contributes to the discussion.
1) Our wiki requires a Textcha for both account creation and for edits.
2) We have one easy question. Something like:
Tired of answering these questions? Enter "yes" and send us an email
with your user id
3) However, almost no one ever sends me an email (but a spammer did once!
:-)
4) Once a month I walk through new logins (about 20-30), searching the web
and my inbox for them.
* I add those that I can confirm to the trusted list (and send them an
email)
* Diable those that are obvious spammers
* Leave the rest alone.
I'm updating this to:
1) Drop the easy question, since no one actually sends me their address.
2) Automate the monthly review process as much as possible.
I'm guessing that change #1 will make my (very small) spam problem go away
entirely.
