Is there anything verifiable in these locations, some sort of rule you need to follow?
Although it is clearly wrong to map this as a restaurant it could be a bus stop with some appropiate tags that ensure a normal map user wont walk there to try to catch a normal bus.

Is there really a bus stop here? It seems unlikely that it would have been missed by the London mappers.

Looking at the users other edits notes/edits this is a personal marker of where a tourist coach should stop.
I think this should be reverted.

Hi, welcome to OSM.
You have added a shelter inside a shopping centre, that seems a very odd place to map a shelter. What were you trying to achieve/

Hi, welcome to OSM.
Thank you for your addition, however Madame Tussauds is already mapped.
See node/29269886
You have created a duplicate node which should be removed.

Hi, welcome to OSM.

Please could you provide some more information, like what its the site of.

Thanks

Hi, something has gone wrong here. You have placed a campsite node in the middle of a road in a built up area. It seems unlikely there is a campsite here. If one does exist, please add it as an area in the correct location.

Hi, something has gone wrong here.
Hashguard cross caravan park is already mapped, hence you have created a duplicate.
I am reverting this change

Hi, you created a guest house here last week, is there any reason you have created a 2nd with the same name?

Hi welcome to OSM. Thank you for your change.
Please remember that osm is a community so please make your changeset comments meaningful and explain what you are changing.
#Accenture #ACCNLDN is completely meaningless.

Hi, welcome to OSM. Thank you for your addition of a bus route.
Bus routes are not tagged as separate ways, however. We map bus routes as relations, if you go onto the transport layer you will see some examples.
Ask if you need any assistance.
Cheers Phil

Reverted maps.me personal annotation of an existing object

I have reverted this, it is a very typical maps.me edit where personal annotations are added to the map. The user probably has no idea he was editing OSM.
As you have said this is a residential area and there is zero chance of a casino being allowed here.

Hi, welcome to OSM. Something has gone a little wrong with this change.

You have changed the name of Burnhervie to be a farmhouse. Please remember that OSM is a public database and edits made with maps.me update OSM.

I am reverting this part of the changeset

Hi, I think this edit has gone a little wrong. There is no building here so it doesn't really belong in OSM, we map what exists now.
Things like this may belong in openhistoricalmap.
Cheers Phil

OSM is a public database, please do not abuse it by adding personal markers.
I am reverting this

Hi, welcome to OSM. This edit is a little odd, alpine huts are really rare in Birmingham.
The name seems to translate as Macka's House which makes it look like a personal marker.
Please remember that OSM is a public database and should not be used in this way.
I am reverting this.

No response and seems unlikely as its on the pavement with a nearby Tesco Express, reverting this

I would also be very surprised if an Edinburgh pub had a chinese name.
The name you have added seems to be a description (Underground Bar), making it appear that it is a personal marker. Please remember that OSM is public database and when you edit you are changing everyones map and not merely adding a bookmark.
