Hey all,
As could be expected the spammers found our wiki (even though it hasn't been publically announced). So I've put two measures in place to combat that:
First of all, to create a new wiki account a Captcha now needs to be solved. This should prevent (most) bots from being able to automatically register an account. Unfortunately spammers have been known to defeat Captcha's (or even pay people to solve them), so this just raises the barrier.
As a second measure, only users with confirmed e-mail addresses are allowed to edit pages on the wiki. This should hopefully prevent spam edits if a spammer gets past the account creation captcha.
All that's needed to confirm an e-mail address it to hit the link in the account registration e-mail. For existing accounts confirmation status can be checked in the e-mail options section of: https://wiki.apertis.org/Special:Preferences
This page also allows one to request an e-mail to be (re)send for confirming if that hasn't been done yet.
Hopefully this combination will prevent most if not all spam, if not there are extra measure we can take but they get gradually more inconvenient/cumbersome on the user/admin side.
