If you're uncertain about something, then don't add it. If you don't
have local/ground truth knowledge you could be adding false data
into OSM. <br>
Assuming third party imagery is accurate is poor mapping & an
example of why i don't like 'tools' such as maproulette.<br>
Add a note to the website asking for local knowledge to check if
something still exists.<br>

How far back should we go? i live in a Roman city. That's a /lot/ of
removed data.<br>

What is 'LSP'?<br>

OSM is not a historical map. <br>

If features are completely removed, then remove the entity
from OSM. If is still in existence but unused the 'disused:'
prefix can be added.<br>

<div dir="auto">I'm thinking about amenities like
