Hi,
I reverted these changesets. Please start slowly with a few edits in a small area and ask your local community for a cross-check before adding huge amount of objects.

Reasons for the revert:

- highways added are mostly duplicate objects already mapped properly
- many foreign tags that should not be in OSM
- useless creation of relations for each way
- the sheer amount of distributed edits in a large area within a short time suggests this is an import of data which needs to follow the import guidelines linked above.

Hi,
you added the tags
radiopolska_name
radiopolska_url
which seem to be duplicates of name and website. Are these tags really needed?

Reminder:

you added some tags here that are not used in any other place. Please make sure you only use those tags that are described in the Wiki or are available as presets in your editor. Everything else is unlikely to be understood by any software and other mappers.

Welcome to OSM!

Please don't just upload any data to OSM. Any import of data to OSM must follow our import guidelines:
osm.wiki/Import/Guidelines

Please check your edits - you uploaded several strange objects without any valid tag like this one:
way/1132661375

Hi,
please check this river, something went wrong with the name tag:
way/1130860837

Hallo,
was hat es mit dem Tag "addr:insurance_number" auf sich? In DE gibt es soetwas eigentlich nicht als Bestandteil von Adressen.

Hi,
these are no common fuel tags:
fuel:B100 = yes
fuel:HVO100 = yes

Could you check the wiki for the correct terms?
osm.wiki/Key%3Afuel

Hi,
you added some tags here that are not used in any other place. Please make sure you only use those tags that are described in the Wiki or are available as presets in your editor. Everything else is unlikely to be understood by any software and other mappers.

E.g.
Number of Connection Roads
Road Material Type
Road Type

Have a look at e.g. highway=*, surface=* or lanes=* tags.

There's a capital "S" instead of a lowercase 's'.

There are still about 50 "Showcase:length":
http://overpass-turbo.eu/s/1q95

OSM is case sensitive, tags need to be written in lower case.

You can use Overpass Turbo for this:
https://overpass-turbo.eu/s/1q8Z

Just click on "Wizard" and enter e.g.
Showcase:lenght=*

You can also get a list of all your edits using the query

Hi,
I found 5 areas with strange keys:

cced_id
comments
e_hold_id
nced_uid

Please have a look and change them to common keys, e.g. ref:XYZ or description

Hi,
please check all your edits for spelling mistakes.
To name a few:

Shocas:length
Shocase:length
Showcase
Showcase:lenght
Showcaselength

Hi,
there is no language ":jp" - the correct code for Japanese is :ja.

Hi,
please don't put the value of a key to the source key.
'source:addr:housenumber' is fully sufficient, there's no need to use 'source:housenumber:XXX'.

Hi,
tags like these are not yet in use in other places:
service:fabrik:repair
service:furniture:repair

The common version is without the 'service:' prefix, just
fabrik:repair
furniture:repair
mobile_phone:repair

The 'service' prefix is only common for service:bicycle and service:vehicle.

Could you check & change that?

Hi,
what does 'fuel:pb' mean? leaded fuel?

Hier scheinen die access-Tags nicht zu stimmen. Was hat es mit dieser Brücke auf sich, dass ein Quad drüberfahren kann, ein Moped aber nicht durchpasst?

Hi,
could you check your destination tags you added recently? The order of subkeys is not the usual one, e.g.

destination:lanes:symbol -> destination:symbol:lanes

The order is always

destination
[:subkey]
[:lanes]
[:backward|:forward]
