Thread:Project:Support desk/Spam protection wiki set-up page anywhere?

Due to working with a version of mediawiki, I can see some major flaws of using it as is. However, I may be missing something, so if I am correct me.

Currently with the base install the following are true...?

There is no spam protection built in (default captcha system for at least sign up) There is no protection from multiple accounts from the same IP being created within say a week of each other (spam protection, w/ or w/o approval, spammers come in hoards) There is no way to *permanently* delete pages (completely remove from the database and purge from disk space by ops, beauracrats) There is no SPAM delete option to delete and remove spam versions of any page.

Am I wrong? These seem to be the most basic functions that would be built into any public access program of any type.

The problem with this is if you have a small wiki and you go away for the weekend; one spammer gets on and by the time you get back you can easily have a gig of spam stuck permanently on your wiki and pretty much have to destroy it and start over.

This brings me back to the original question; is there a page that has detailed instructions on how to set-up and meet the above four spam protection requirements?
