I hadn't gone, I had it from here https://www.mapillary.com/app/?pKey=1094373074390518
I just updated from more recent imagery.

Thank you @woodpeck for the clarification and the link. My point was that the tags where better before SimonPoole's edit : a "trolltag" (which some consumers cannot process) is always better than a typo (which cannot be processed at all).

I have only opened 3 of his changesets and there is already 33% mistake. I haven't checked the rest of his edits.

You changed a correct spelling with an incorrect one, and accuse GreenRunner0 of putting "troll tags".
The only troll is you.

Καλησπέρα, έχει αλλάξει η πινακίδα στο δρόμο;
Ρωτάω γιατί πχ η οδός Τζαβέλα δεν έγινε А. Γρηγορόπουλου, αλλά η οδός Θ. Γαζή έγινε Άλκη Καμπανού.

Σε κάθε περίπτωση, name είναι αυτό που βλέπουμε στη πινακίδα, κρατάμε ως old_name το προηγούμενο, και ως alt_name το εναλλακτικό.

Yes I remember being there. Their customers are mostly industries. Their website's thumbnail reads "Technical raw materials & composites", if you find a better tag than "plastic" please change it.

1) There's example of other country which surprisingly changed the maxspeed without notifiying cartographers first. You will not hear of the plans until they happen.

2) Please send me mapillary (or google street view) which proves the street sign maxspeed=140 and then I will re-tag as you say.

We only tag what can be verified on the ground, and since there is no 140 speed sign so we cannot put maxspeed=140

If there is no explicit maxspeed, we put the implicit maxspeed BG:maxspeed.
maxspeed=*#Implicit_maxspeed_values

If we wrongly put 140 and the law changes, then we must re-tag all the country. BG:motorway keeps us safe from law changes.

On second thought, where the maxspeed=120 is over, I should have used BG:motorway
I'll do it now.

And where there was a sign that the 120 speed limit is over, i removed the tags.

The speed limit was wrongly tagged 140 where the sign says 120.

Please put the stop signs ON the way (not next to it). highway=stop

Καλησπέρα Σεραφειμ, τι είναι αυτό το poi που πρόσθεσες εδώ; node/9419608106/

hello, what is this poi that you've added here?
node/9056626110/

Was is still named Pita Pan? I cannot find it on their map https://www.pitapan.gr/katastimata nor on the footer of that page nor on their FB where they mention the other branches.

You also put int_name=Karolou Koun street. We dont put "street" in the int_name (and we don't map in english either). /

hello Raenbow,
we don't put "street" in the int_name, we only copy what we see on the street signs.

Hello tadams, you have marked that Pita Pan is accessible with wheelchair, but i cannot see the branch in their website in the first place node/3984600839/history

is it still Pita Pan or is it another fast food accessible with wheelchair in the same place?
