Thanks for the answer. I just found this thread in the forum:
https://community.openstreetmap.org/t/flock-safety-weird-mapping-pattern/128339
In post no. 7 someone claims to be in contact to the website operator. So maybe there will be an update/improvement on the website of deflock.

Did deflock reply to your request? There is currently 20x operator:wikidata="(WikiData ID)" in the database. So people keep adding it.

The source should not be added to this changeset.

Hello Nesim,
you added address-data to this objject:
osm.org/node/3213664480
city=* could be removed, but addr:street=* and street=* have different values. Could you have a look again? Thanks.

Hello cloudVoicerHub,
you removed all members from his relation:
osm.org/relation/2216823
Was that an accident?

Thanks for the context. I think now it is sve to say that the tags got added by accident. I just removed the tags from the node:
osm.org/changeset/166124697

I just mearged the 4 emergency=disaster_response into a single node:
osm.org/changeset/166123372

Hallo Neslihan Güzelsoy und wilkommen bei OpenStreetMap!

Du hast hier ein Objekt angelegt, das ich nicht ganz verstehe. Worum handelt es sich hier?
osm.org/node/12816683792
addr:country=hamburg kann so nicht stimmen. Sollte das vielleicht addr:city=Hamburg; addr:country=DE heißen?

Thanks for the quick reply. I just fixed that.

Hello Hikerandy,
you added some signs here, for example this one:
osm.org/node/8400997983
I think name="No Entry" is not correct as this is probably not the name of the sign. Could you check if inscription="No Entry" would be fitting?
osm.wiki/Key:inscription
Thanks

Hello Makang,
you added street=Koda here:
osm.org/node/9481336211
Is that a typo for addr:street=Koda?
In this area street=* is used 200x:
https://overpass-turbo.eu/s/23Pi
This tag is undocumented. Do you know something about that? Are they all typos for addr:street=*?

Hello Felixcollins and welcome to OSM!
It seems taht you added an address here:
osm.org/node/497457762
It is located in the middle of London but you added addr:country=Netherlands. Could you please check that out? Please use "GB" for Great Brittain and "NL" for the Netherlands.

Hello ch4nd3y and welcome to OpenStreetMap!
You added this object to the map:
osm.org/node/12732471492
Unfortunatly you used an unusual combination of tags. What exactly is this? Is it a school?

Ist erledigt:
osm.org/changeset/165806559

Danke für die Rückmeldung. Das kann ich gerne machen. Hat das "Dlich>" irgend eine Bedeutung oder kann ich das einfach mit "DE" überschreiben?

Hello Akbar-Birbal,
you added a strange addr:country here:
osm.org/way/1288035543
Did you mean to add the housenumber instead?

Hello avidmohajerani1 and welcome to OpenStreetMap!
You added some tags here that dont make much sense:
osm.org/node/3746861133
Could you describe to me what this is?

I removed the placeholders for now but I noticed that these got added in the past from different users. I now found the instructions at https://deflock.me/report/id. They seem to be the reason for those edits.
Thanks for reaching out to the service. Please contact me if they answer something.

Hello Annie khalid and welcome to OpenStreetMap!
I have some questions about a gas station you mapped. Could you have a look?
osm.org/note/4741740
Thanks.
