<p>This problem is well know, and not new, but still needs to be solved.</p>
<p>All of the user-related urls, like diaries and even user profiles, use the "display name" in the url, which can be changed by the user, e.g.</p>
<p><code>https://www.openstreetmap.org/user/Andy Allan</code></p>
<p>This makes it impossible to create stable links to users or their diaries etc, and users can hamper communication and anti-vandalism activities by repeatedly changing their display name.</p>
<p>The urls need to be stable. One way to achieve this would be to use the user-id instead of the display name</p>
<p><code>https://www.openstreetmap.org/user/4115</code></p>
<p>The user id is already exposed in the API and used by third-party services, precisely because the display name is unstable. We could do the same on osm.org. </p>
