<p>In addition to <a href="https://stats.meta.stackexchange.com/a/2708/89026">gung</a>'s answer there are some things you can do if you notice a pattern of bad edits from a user (regardless of their rep).  </p>

<ol>
<li>Ping them in chat, if they've used chat before.*</li>
<li>Talk to a moderator in a private chat room, and let the moderator handle the issue.</li>
</ol>

<hr>

<p>*: I would like to extend an open invitation to everyone to ping me in chat if they think I'm doing something wrong.</p>
