They have been moved, not removed. No information has been removed.

Please keep to accepted names. The Oval is one of the most famous cricket grounds in the world. I cannot imagine that Test match Special will start calling Kia Oval anytime soon.

Hi, I think you have got this wrong. The Tigers play at Welford Road. The term stadium is never used. I suspect the site you are copying from has got some duff information from somewhere.

You should also be aware ofthe import guidelines
osm.wiki/Import/Guidelines

You cannot get permission for google maps, but you do need permission from the website for their work to be reproduced without restriction.

Personally I find it simpler to map places I have actually been to.

Everything you need to know about copyright is in https://wiki.osmfoundation.org/wiki/Licence/Licence_and_Legal_FAQ

Well you still need explicit permission to use that information, database rights will apply to any collection of facts.

My opinion is we must not even use Google maps to even do that.

Seems to be using Google maps which we must not use.

That seems to be Australia.

Hi, this edit covers quite a large area. What sources did you use to locate these objects?

Cheers Phil

Dave has discussed it with the GB community.

And the task says nothing about adding them in different parts of the world.

Hi Enock, I cannot see any emoji and wouldn't understand it if I could.

Hi
Please could you keep your changesets to a sensible size and use meaningful changeset comments so that local mappers are able to understand how they affect their areas.
In this changeset you have added buildings on muliple continents, please split these changes into smaller geographic areas.
Cheers Phil

Hi, welcome to OSM. I have removed the area you added as it matches nothing that exists on the ground and an area tag without another tag is pretty meaningless.

What were you trying to map?
Cheers Phil

Hi, the correct way to mark a pub as disused is to change the tag to disused:ameni=pub rather than add a disused=yes tag.

Hi, we do not map short term closures in OSM. Navigation software takes periodic samples (monthly) and hence this could mean that the sliproad is not available until the middle of September.
I am reverting this change.
Cheers Phil

Hi, thank you for your edits but please keep the name tag for actual names, it should not be used for descriptiions. I have changed these to man_made=rock_armour which fits them better. They are not places or islets.
Please could you also use meaningful changeset comments that describe what you are doing. Tidying doesn't really say much and in this case you were adding sea defences and not tidying at all.
If you need help or advice, just ask,
Cheers Phil

I recently surveyed the signs on this section and can confirm that the edit made by Brian was correct and matched my survey of the signs. The correct OSM mapping is always what we see on the ground.
Please revert these changes.
Cheers Phil
