<p dir="auto">Right, then perhaps this won't be that useful. Having said that, I wonder if this could be useful against less sophisticated actors. I don't have access to the DB so I can't answer this question: do we see any correlation between accounts flagged for abuse, and the "repetiveness" of their <code class="notranslate">users.creation_addr</code>?</p>
<p dir="auto">As for the implementation detail, what I was thinking was running something like the following on user creation:</p>
<div class="highlight highlight-source-sql" dir="auto"><pre class="notranslate"><span class="pl-k">UPDATE</span> users <span class="pl-k">SET</span> count_users_in_ipaddr <span class="pl-k">=</span> count_users_in_ipaddr <span class="pl-k">+</span> <span class="pl-c1">1</span> <span class="pl-k">WHERE</span> creation_addr <span class="pl-k">=</span> ?</pre></div>
