I made a new site and it immediately got taken over by spam. It was quite a hassle to delete all the spam and all the users. Not to mention that it was very unclear how to do this.
I am wondering why the captcha is not enabled by default. It seems to me that the by default the OpenID extension, mass delete extension and the BlockandNuke extension should be enabled.
Finding, installing, figuring out how to use them tool several days of work.
Why is the default version of Media Wiki so vulnerable to spam? How can we make it so users who are not that savvy do not get completely overrun?
