Hi there and welcome to OSM!

When a POI does not exist anymore (but the place is prone to used by another POI at some point) we do not delete things, but mark them using the https://wiki.openstreetmap.org/wiki/Lifecycle_prefix. That way special apps can ask the user if e.g. a shop is occupied again after some time has passed.

I have already done that for you. You can see how this looks like here https://www.openstreetmap.org/node/1654315036

Feel free to visit our monthly Bremen community meeting if you find the time. Further info on that here:

General advice: take it slow, ask a lot of questions and do a lot of reading :-)

If you have questions, let me know!
