<p>Without calling anyone out, I suspected someone of downvoting other answers than their own just to have theirs appear higher/attract more upvotes. However, I wasn't sure how to report this and more importantly, I had absolutely no evidence, just a suspicion. Several days later I went to check again and saw that this user was banned for irregular voting patterns, so I can only assume this was the reason. </p>

<p>My question is:  </p>

<ul>
<li>Is this indeed a bannable offense?</li>
<li>How, if at all, should this be reported?</li>
</ul>
