Topic on Project:Support desk

Hello, I have been using wiki for a short time with the intention of having a collective creation space for 7 people.

This month it has been hacked and there are more than 18 thousand users who upload hundreds of pages of irrelevant content.

What do I do to?:

1 Retrieve my content

2 Eliminate the rubbish introduced

3 Prevent new users with or without registrations from uploading content

Thanks for the help

as an aside, getting spammed and getting hacked are different things.

There is some advice on manual:combatting spam
