Hi! I updated the wiki page with Mapbox mention. I should say that on the
list of organised editing/activities there's mention that this project is
from Mapbox.
https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities
You're right about turn restrictions. We always try to find street-level
photos to map or fix it, but sometimes we use only aerial photos.
In the end of each iteration I will add some examples of our fixes in the
related ticket.
Thank you for your advice, we will keep it in mind!

Best regards,
Sonya.
