<h3 dir="auto">Problem</h3>
<p dir="auto">DWG often has to deal with users creating multiple accounts (sock puppets) in order to abuse features of OSM.</p>
<h3 dir="auto">Description</h3>
<p dir="auto">Detecting sock puppet accounts is tricky. A first approach could be using the <code class="notranslate">creation_address</code> and check how many other users were created from the same one, as follows:</p>
<ol dir="auto">
<li>Add a column <code class="notranslate">users.count_users_in_ipaddr</code>.</li>
<li>On user creation.</li>
</ol>
<ul dir="auto">
<li>Find any other users with the same <code class="notranslate">creation_address</code>.</li>
<li>For all of them increase their <code class="notranslate">count_users_in_ipaddr</code> in one.</li>
</ul>
<ol start="3" dir="auto">
<li>Show this number... where exactly? TBD</li>
</ol>
<h3 dir="auto">Open questions</h3>
<ul class="contains-task-list">
<li class="task-list-item"><input type="checkbox" id="" disabled="" class="task-list-item-checkbox" aria-label="Incomplete task"> If this was implemented, where would this information be useful and to whom? Ideas below, to be accessible/visible by moderators:
<ul dir="auto">
<li>A page listing users with high values of <code class="notranslate">count_users_in_ipaddr</code>?</li>
<li>A number next to the user name, wherever relevant? Eg: changesets.</li>
<li>In the <code class="notranslate">/issues</code> list?</li>
</ul>
</li>
</ul>
<p dir="auto">To discuss with DWG and maintainers.</p>
