Hi folks. As I'm sure most of you know by now, this problem is increasing
dramatically in the last few weeks. Big sites like redhat
(http://sources.redhat.com/lvm2/wiki/RecentChanges), x.org and so on are seeing
these wiki spams by auto-created users (XXXjingkeYYYY, caicaimmXX, and many
others). I run a small wiki for scons.org, and we don't have the resources to
despam every day. We need a captcha plug-in to prevent bot registration; we've
already turned off anonymous editing but it doesn't help anymore.
I looked at Russell Stuart's Email Activation, but self-activation could be
trivially implemented by these bots (they have valid rDNS and everything), and
the last thing we need is a human admin in the registration loop.
What's wrong with recaptcha (http://recaptcha.net/)? It's a decent captcha
system, and it helps scan old books (a CMU project). It has audio for the
visually impaired, and has a simple two-function python API, see
http://pypi.python.org/pypi/recaptcha-client.
Can someone at least tell me where to plug it in? It's getting past the painful
point. (BTW: I'm posting this via gmane, and it's making me solve a captcha
just to post this.) Please reply to me at garyo at genarts dot com as well as
to the list.
