Lately I've been noticing more and more spammers on this wiki. It makes it kind of annoying to read pages and then see spammed messages at the bottom not relating to anything. These spammings are annoying and I've seen people telling them to stop spamming also.

What do you think should be done?

Should they get blocked after a certain amount of Spamming? Or should pages start being locked?
