Editors such as this should be following 
https://wiki.openstreetmap.org/wiki/Organised_Editing_Guidelines .  The 
users here are clearly not doing so:

https://www.openstreetmap.org/user/VLD174 has no link from their profile 
page to entries in 
https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities for 
projects that they are working on (and in fact there currently seem to 
be NO entries on that page with Facebook as an organiser).

https://www.openstreetmap.org/user/VLD071 doesn't mention Facebook 
directly either, but does mention's Facebook's "black hole" address 
"osm at fb.com".

It's not the first time that Facebook's mappers have been found wanting 
- see e.g. https://www.openstreetmap.org/user_blocks/4171 and other 
previous occurrences.  My impression (based on looking at the results) 
is that Facebook's mappers receive less training about what OSM is and 
how the various communities work than some other "organised mappers".  A 
write-up from the Facebook side of an early attempt at adding stuff by 
them is at https://news.ycombinator.com/item?id=17856687 (that was 
completely reverted by the DWG because it was complete garbage - any 
vaguely straight line was added as a "road").

It's good that in this example you've managed to make contact with the 
Facebook mappers concerned and the damage has been reverted, but I 
suspect that we (the DWG) do need to have a chat with Facebook about 
what they need to do to follow 
https://wiki.openstreetmap.org/wiki/Organised_Editing_Guidelines .

Best Regards,

Andy (from OSM's Data Working Group)
