[OSM-talk] Spam spam spam spam

[Richard Fairhurst]

Our lovely little mapping hobby is now so uber-successful that the  
spammers have noticed it. A few more keep creeping through the net.

What should a spam-spotter do on noticing some spam?

I've pasted a few I've spotted here:
http://wiki.openstreetmap.org/index.php/Spam

but am unsure what to do about it. In particular, on the wiki, is it  
simply a matter of deleting all content from the page, or does that  
leave it in the history for spiders to pick up?

cheers
Richard
