<p>As osm grows the chances that somone will try to damage the map grows.</p>
<p>Maybe a new user should have their edits checked when they first join and then build trust that way. Make it a random check but put the priority on the new users. If somone does a large edit then it can be flagged to be checked etc.</p>
<p>A photogallery system called <a href="http://fotopic.net">fotopic.net</a> uses this kind of system to stop new users uploading pornographic images.</p>
<p>It should only take a few trusted users to check on things.<br></p>

working for almost a year with a lot of the map data, I have not seen any<br>
piece of intentional vandalism.<br>

Or, an even more opposed case: A couple of day ago somebody added arabic names<br>

</font></p>Even something simple like the bus route I've added yesterday might easily<br>
touch more than a hundred elements. On the other hand, you could damage<br>
significantly the map with less than a hundred destructive edits.<br>

I personally do a lot of mapping in my holidays, so a pattern like massive<br>
activity from time to time will appear from the system's point of view. On<br>
the other hand, it is easy to tune the amount of activity of a malicious bot<br>
to any pattern expected by the server as "regular".<br>

There might be a lot of use cases, e.g. naming things, adding POIs, bus routes<br>
and so on that require no GPX data at all.<br>

these frills? There might be users who can't contribute something useful in<br>
one or more of the above systems (What should a non-programmer contribute to<br>
the SVN Repository? Should every user write wiki pages that nobody wants to<br>
read, just to display honest acitivity?) or just aren't interested in certain<br>
tools (not everybody wants to blog).<br>

intervention by lawyers which comments are admissible and which aren't?<br>
<br>
An implementation of the whole idea would not only take a lot of ressources of<br>
the implementers, but also affect significanty normal users. The way mappers<br>
and other users use the system in a legitimate way is so widespread that any<br>
reputation system would end up bullying a smaller or bigger fraction of the<br>
users. Remember that the API has intentionally been kept small to make usage<br>
simple. On the other hand, there is no strong need to prevent vandalism<br>
because there is only sparse vandalism. So I would suggest to keep the whole<br>
concept away from the map.<br>
<br>
