Does Volenti non fit injuria work?
<p>There is <a href="https://en.wikipedia.org/wiki/Volenti_non_fit_injuria" rel="nofollow noreferrer">Volenti non fit injuria</a>.</p>
<p>I'm confused whether if there is app where users can offend each other (what is illegal), but it requires user consent while registering that he accepts all things that can be done here to him (hate etc.), then can that app work legally? Could offending in such an application be legal and without consequences?</p>

<li>Some people seem to believe that just because something happens 'in the internet' it is somehow outside normal jurisdictions.<br />
<strong>Wrong.</strong><br />
In may be harder to investigate and prosecute crimes in the internet, but the laws apply all the same. There are some problems when it is unclear 'where in the world' something did happen -- in the jurisdiction of the perpetrator, the victim, or the service provider? But problems of jurisdiction apply e.g. to international fraud cases in the non-web-world as well.</li>
<li>In many jurisdictions, the informed and voluntary consent makes <em>some</em> things legal which would otherwise be illegal.<br />
For instance, if two boxers get into the ring, it is understood that each of them did consent to be hit by the other. But usually two fighters could not legally agree to a fight to the death, because even if there are laws on assisted suicide, they do not apply to a fight.</li>
<li>Insults, libel, and slander are not on the same level as homicide. There are jurisdictions where they are not prosecuted without the request of the victim. But an insult might also violate other laws, e.g. disturbing the peace. So don't bet on such an app unless you know <em>for sure</em> which jurisdictions are involved.</li>
