<div>Can you name one tag that is "forbidden"? Does that mean a standing instruction to all mappers to remove it whenever it is found, or a license to do a seek-and-destroy across the whole database? Or does "forbidden" not quite mean "may not appear in OSM"? "Frowned upon" possibly.</div>

<div>I would say that</div>

<div>applies to several things (listed below).</div>

<div>Is there any case of a whole class of objects being removed from OSM on the grounds </div>
<div><span><span><span class="font" style="font-family: Roboto, sans-serif;">that they "do not belong"? Who would burn their fingers on that?</span></span></span></div>
</div>
<div>Depends on what you mean by "whole class of objects".</div>
</blockquote>
<div>Class, category, whatever... A subset of the objects in the OSM data with common characteristics.</div>

<div>We have precedent that entire classes and types of things are</div>
<div>out of scope.</div>

<div>Where is that written down? What classes and types of things have been declared out of scope? </div>
</blockquote>
<div>For example things that I immediately remember</div>
<div> </div>
<div>- fictional objects</div>
<div>- blatantly subjective things like reviews, ratings</div>
<div>- mapping of private objects (location of my bed)</div>
<div>- mapping of moving objects (location of myself or a moving ship or plane)</div>
<div>- completely gone objects (for railways the question is when railway is fully gone)</div>
<div>- personal detail (ties into subjective ones) like "my favorite trees", or "towns I visited"</div>
<div>- objects on Moon/Mars and other locations outside Earth</div>
<div> </div>

<div>Objects with these characteristics cannot be (easily) identified in the data - they would need a human to judge on a case-by-case basis (except for the extra-terrestrial things, but you might have trouble defining their location in terms of WGS84 lat/lon anyway...)</div>
<div> </div>
<div>Subjective data is by definition not independently verifiable, so that can go. Ratings are sometimes awarded by a recognised body (rather than by customers), and those ratings would IMHO qualify as independently verifiable.</div>
