Witaj,
z tej strony Andy z Grupy Roboczej ds. Danych (Data Working Group) w OSM. Czy możesz wyjaśnić, skąd wiesz, że dane, do których przywróciłeś stan poprzedni, są poprawne, a wcześniejsza edycja była błędna?
Pozdrawiam,

Hello,
Andy from OSM's Data Working Group here. Can you explain how you know how the previous data which you reverted to is correct and the previous edit is incorrect?
Best Regards,

¡Hola, J00SECI, y bienvenido a OpenStreetMap!
Sería de gran ayuda para otros colaboradores que pudieras ofrecer un poco más de detalle sobre lo que estás añadiendo, en lugar de indicar simplemente «Cambios varios».
Saludos,
Andy

Hello J00SECI, and welcome to OpenStreetMap!
It would really help other mappers if you could give a bit more detail about what you're adding, not just "Cambios varios".
Best Regards,
Andy

> along with some information from Google Maps.

For the avoidance of doubt, you must not use Google Maps as a source. Google's terms and conditions are incompatible with OSM's licence.

こんにちは。
このデータの出典は何でしょうか？「現地の知識」に基づくものというより、どこかから取り込まれた（インポートされた）もののように見受けられます。
よろしくお願いいたします。

Hello,
What was the surce of this data? It looks like an import, not "local knowledge".
Best Regards,

Just guessing, but it possibly let you save it because it's part of a relation?

Even the name was added by the spammer, so it makes sense to remove that too.

Like with changeset/187065244 , you fixed the phone number of some obviously misplaced SEO spam _again_ ! :)
Do you really think that it is plausible that "Royal Caribbean Cruises" is run from a small house in the suburbs of Orlando?

Hello,
Alas, if you look at https://map.atownsend.org.uk/maps/osm-deep-history/#/relation/2185374 you can see that they changed a couple of other keys as well, which haven't been changed back yet.
Would you like to do this, or would you like me to?
Best Regards,
Andy

Thanks - who were the project organisers, how can I contact them?

Thanks - reverted in changeset/191009031

Hello,
Are you sure that this company actually operates in the UK?
