Thread:Project:Support desk/Too much traffic

I started a Wiki: http://solidarity.coop/wiki

For weeks it had hardly very few visits, then since two weeks ago the traffic has increased sharply. If it continues at this pace I can't afford the hosting costs.

Traffic stats: http://i.imgur.com/pHoCge9.png

I don't think the traffic is organic, there's very little content on the wiki, but I did notice lot's of spammers. I've clicked 'protect' so they can't change pages anymore, but it seems they are still visiting.

Any idea's?
