My wiki has been the target of spam recently. Yesterday when I went to it, the content of the main page was gone and was replaced by spam links. One of the nice things about wiki’s is was easy to revert to the original page.
I couldn’t figure out how this was happening. I disabled anonymous editing, yet pages were still being modified. I finally did a little research last night and found out that the spam bots were actually creating wiki accounts and then modifying pages under an account. Since my wiki is strictly for my own use(at least for editing), I don’t need users accounts at all. So after a little more research, I found a line that I could add to the configuration file that only allows admins to create user accounts. I’ve instituted that and it does remove the user creation form from everyones view. Now I just hope it works
