Openstreetmap had its first spam yesterday from someone uploading a html file (a web page) as a GPX file (a GPS trace file). Being XML (similar format), it got parsed and uploaded with spam-like tags linking to the individuals business. The point being that google etc would crawl the pages and increase his page rank. It exposes the soft underbelly of openstreetmap’s policy of crossing bridges when we get to them – we’ve only had good bridges so far!
