software
Is there any legal way to stop specific websites from offering nulled versions of my software for free?
<p>Last year I wrote a piece of software that functions as an accessory application for a large forum software suite. </p>

<p>Specifically, it is an "Application" for Invision Community.</p>

<p>You can find other similar applications for the same software here: <a href="https://invisioncommunity.com/files/" rel="nofollow noreferrer">https://invisioncommunity.com/files/</a></p>

<p>I'm unsure how these files are licensed, however I charge $30 + $15/6mo for my application. Recently, an unknown member who purchased it released it on a popular <code>nulled</code> software website where people upload paid software packages for free for others to download. Since then, my sales have dropped to nearly $0 for the package.</p>

<p>I'm curious if the licensing of Invision Community leaves much room for me to do anything, or even if it does, if there is really anything I can do about this.</p>

<p>On the face of it, this is blatantly illegal copyright infringement, for which there are legal remedies. However it is impossible for us to know whether you have inadvertently released the software into the wild, not understanding the terms of use for the website. Since the site does seem to prevent passers-by from freely downloading files and they do charge for content, it is reasonable to assume that (1) you have granted some license for the company to distribute your software and (2) customers are actually told that they can't just post stuff on piracy sites. </p>
