Alright, I guess the tags can be removed.

There is a possibility to add 'sidewalk=separate' to the main road to mark that there is a sidewalk mapped separately, but it's not needed on the sidewalk itself.

Hi,
please check this road, it got two strange tags:
way/31237118

crossroad = aisle
osm = tag

Hi,
you introduced several new (complicated) parking* tags here. Please have a look to the wiki how the current tagging scheme looks like:
osm.wiki/Street_parking

Hi,
adding maxweight=3.5 is the correct thing to do. Somehow you also changed all other tags on the bridge. I restored them to the version before your edit, as you can see in the history of the way:

way/161607973/history

Hi,
you used the tag 'separate=yes' here - did you mean 'segregated'?

Why did you remove this bridge? Has it been destroyed?

Please let me remind you about the comments I made on changeset/129546085

This import again violates our Import Guidelines and the Tagging rules. You must not ignore 1490 warnings and errors shown to you before uploading.

Hi,
please check this building, it got a strange "building:architecture" tag.

All tags I removed were not correct.
Please check the Wiki, "zł" is not a valid currency code.

Hi,
please check your edits. You uploaded 33 strange objects like this one:
way/1123596514

Hallo, was sind denn "ground:levels"? Meinst du
building:levels:underground ?

Hi,
"male_haircur" is definitely a spelling mistake which needs to be fixed.
A proper currency code is missing as well.

The question about how to tag prices of services pops up every now and then on the diverse discussion channels. The answer always is an unambiguous "we don't want this kind of information in OSM". So I decided to follow this advice and not fix the spelling.

Hi,
you uploaded two ways like this one:
way/1121692007
They don't have any proper tag and I can't verify them on aerial images. Please check & fix them.

Hi,
you edited more than a hundred aeroway objects and added the tag "aeroway:area". This tag is new and not used in other places. The common and documented tag is "area:aeroway". Please have a look and change the tagging.

Hi,
was heißt socket:CEE? Bitte schau im Wiki nach den korrekten Namen der Stecker:
socket=*

Hi,
I guess you have to ask ZeLonewolf who added these two lines.
It seems that one is from Tiger data and one from the city council...

Here you are:
changeset/129961742

Hi,
the language code 'dk' doesn't exist. I guess you mean Danish, this would be 'da'. Could you check / fix that?

I'll revert this import for now. Please read and follow our Import Guidelines for any import of data to OSM.

Hi,
please check the destinations you added. There are about 100 ways with keys like
destination:lang:backward
destination:lang:forward

They are missing the language.
