Welcome to OSM! Please notice this is a production database.
Please only draw in existing objects and facts. I have now reverted your changes.

In that case, shouldn't it have been ref:wof?
I also suspect that Wof's licence is not being complied with: https://whosonfirst.org/docs/licenses/ (directly in the first sentence). In this case, I would not recommend documenting the key in the wiki, but rather deleting it directly.

Hello! What is the mean of the key wof:id = 1813706845?

Welcome to OSM! Please be careful! You moved the node node/4270102194

I moved the node back to the original position.

Hello! Please have a look on node/13319479734. What is the mean of the tag Грабовача = heath

Welocme to OSM! Please have a look on node/8591392953. What is the mean of the tag 廃駅 = 歌志内?
Please notice we use british english for the keys (and values, if they are countable).

Corrected! We are all human beings, and human beings make mistakes, even if they are not new. Have fun with OSM!

Hello! If you're already drawing in parking routes, wouldn't it make sense to delete the lake as well?
see discussion on changeset/174478608 (allowed sources)

By the way did you mean really addr:unit instead of addr:postcode?

Welcome to OSM! Please do not add the ‘building’ key to the property, but only to a building.

Hello! You write "Anza Center" but "ANZA AV". Please use always mixcase writing of names.

Welcome to OSM! Thanks for your addition!

You only added the name of a business to the building, but did not note that there is also a business there. If you do not know the spelling of the tag, please look it up in the wiki osm.wiki.
