Please don't use the main, global database of OSM for you own tagging tests. Nobody else is able to use this data.

Your activity also seems to be what we call "organised editing" and needs to follow certain rules: https://osmfoundation.org/wiki/Organised_Editing_Guidelines

Hi,
please check the tags you added here - almost all amenity tags are not correct.
Please use only tags that are described in the Wiki.

And: What is the meaning of "searchable=no"? nobody else uses these tags.

Hi,
is there really a village here? I can't find anything in the aerial images.

Hi,
you added "addr:postnumber" here which seems to be a mistake and should be "addr:postcode"?

Hi,
hier gibt es einen Tippfehler bei "handrail":
way/111744001

Hi,
some of these trees got a "powierzchn" and "podtyp" tag - these are not used in any other place. Could you explain what they mean? Maybe there is already an established tag for this?

Hi,
you used some uncommon tags here - could you check the wiki how memorials or monuments are usually added in OSM?
E.g.
historic=memorial

That wasn't on purpose - sometimes I forget to check the exact location of the edits - there is no automatic warning like in JOSM.

Thanks for the explanation! For these we have a dedicated tag:
highway=speed_display

Hi,
you added "SIMULADA" / "SIMULADO" / "sIMULADA" tags to several speed cameras. These are not common - what do you want to tag there?

Hi,
you added some complicated opening hours here - unfortunately they won't be supported by any application - the tag doesn't foresee to add free text to the key.

If hours are so complicated, the best is to simply link to the official website using "opening_hours:url"

Hi,
is there really a public footpath right through the backyards of these houses and a garden stretching through a dozen buildings?

Hi,
you added a huge number of payment tags to an optician. These tags are not used in any other place - it is not common to add all possible insurance compenies as payment methods.
It's usually sufficient to add
'payment:insurance=yes'

You could additionally list the insurance companies in 'insurance=ABC;DEF;XYZ'.

Hi,
here are 4 ways without proper tags, could you check that?
e.g. way/1467721224

Hi,
could you check your edits and the tag suggestion in your editor? I guess it should be "survey:date" and not "surgery:date".

Hi,
please check your edits. It should be "building=construction", not "constraction=yes"

Please check your edits. It's "building", not "buillding".

Hallo,
was ist denn "building_was = house"? Wurde hier abgerissen?

Hi,
"fuel:two-stroke_mix" is not a common tag - which of the documented fuel types is this? fuel:1_50, fuel:1_25?

Hi,
could you check the languages? There's "language:t" which is a mistake.
