Hi fatehah ali, please do not enter empty keys.For each key you can finbd help here:
name=*
Thanks, Alex

Ich korrigiere immer anhand des OSM-wiki, und suche Fehler via taginfo. Wobei ich mich meist auf das Format beschränke, und nicht die 2nd-language entferne (obwohl sie eine Ausnahme sein sollte), um niemanden durch Löschung seines Tags zu verärgern (ausser es ist ein offensichtlicher Tippfehler). Evtl. könnte man eine automatische Korrektur oder Warnungsmail an den Verfasser schreiben, bei typischen häufigen Fehlertypen. Kennst du dich diesbzgl. besser aus? VG, Alex

Hi samely, you entered 8x tag "1"="yes", e.g. way/379682013. This seems to be a typo, as it has no meaning. Could you please fix it? Thanks, Alex

Hi loumoi, you entered 8x ways/buildings having tag "1"="yes", e.g. way/473514462. This seems to be a typo. Can you fix this, as it has no meaning at all. Thanks, Alex

I changed it to name, as the neighboor-ways. Alex

Hi johnny, what means "1"="Calzada Jardín Corona" ?
see: way/467271122
Could you please fix this? Thx, Alex

Hi Jeffrey, what means tag "2=80" in way/476773448 ?
I made it a note. KR, Alex

hi Sparks, you added a way with many broken tags, see way/475564141/history .
Pease try to correct this, because most of these tags are unique and not part of OSM wiki. thx, Alex

Hi hadidoki, you added many useless keys to way/169379799 . Please be more carefull.
KR, Alexander

Hi nitrofurano, you added many times the invisible character 0x7F into names of ways in South-Amrica. They cause different problems and are invisible with some tools, Please take care. Thanks, Alexander

Hi tren_sur, I fixed a bad key in way/133684806 . I think this was a typo. KR, Alex

hi vt100, i fixed 2 tags in your changes: 5=1 and 4=1. I assume they were typos, but anyway they have no meaning.
Best regards, Alex

comment wrong, not river but highway

Hi iWowik,
1. sorry, I did not want to hide it.
2. sorry I cannot read russian text (your err-page)
3. I saw some other frequent problems in wikipedia tags. Could you check this too? OSM wiki tells, to use wikipedia=lang:Name, not wikipedia:lang=lang:Name, or wikipedia:lang=Name(as only wiki-tag), wikipedia=*#Examples
Especially wikipedia:ru=ru:* is seen often.
Many Regards, Alexander

Hi iWowik, please follow the osm-wiki (wikipedia="lang:Article Name").
E.g. node/3479309600
see details: wikipedia=*#Examples
Thanks, Alex

hi A., please concider OSM-wiki, see: wikipedia=*#Examples
wikipedie="lang:Article Name" ,
Thanks, Alex

Hi zstadler, could you please fix "d"="d" tag.
You inserted it at node/1166158561
Thanks, Alex

please check, way/435702970/history
I fixed it. As it is invisible in many views, you have to copy the name to a tool that shows all chars.
Another example (another changeset, perhaps another user),
https://taginfo.openstreetmap.org/tags/name=Carrer%20de%20Josep%20%7FMaria%20Caparr%C3%B3s
These special char makes it impossible to search! You need some hacks to locate them! There are about 500 objects in OSM withc such names. And about 80% was entered by 3 users mostly last year !

Hi JLZ. please follow the OSM-guidelines for wikipedia key. wikipedia="lang:Name"
wikipedia=*#Examples
Merci, Alex

Hi jconstanti, you inserted an invisible char (ASCII 0x7F - its only to be ignored) into many names during last year into Spain. E.g. way/435702970 . Invisible means: depending on tool, they are seen or not.
These strings are not searchable and sometimes not rendered correctly. KR, Alexander
