Is it a wetland or a water? If it is not wetland then wetland tag should be deleted, if it is a wetland than natural=wetland rather than natural=water should be used

node/308078284

is it really valid/wanted for this address node to be a part of boundary zone relation?

incline=up++
was used here, see way/1424459224/history

Maybe
incline=up
was intended here?

I am pretty sure that it is a typo, but not sure enough to just replace it (I edited some objects where situation seemed more clear to me).

Or maybe this value was used deliberately? In such case, what was the intended meaning?

If you know it is a mistake - can you fix it?

node/940287541/history

is Teboil D Pirkanhovi (shop=no) closed all the time? Then almost certainly it should not be tagged as shop=no

And if it is not always closed then opening_hours=closed is wrong

For closed shops that are vacant/rebuilt/etc tagging like disused:shop=no would be better

node/6331351425

Or has it been repaired in meantime?
