[OSM-talk-be] talk: "responding to vandalism"

[Yves bxl-forever]

The idea is interesting.  Wikipedia uses a similar process: edits by anonymous or new users are flagged as potentially suspicious, and users can validate contributions by other users.

I understand Karel’s concern: perhaps that there isn’t much *vandalism* in OSM in Belgium so far.
But the problem may be that newbie-friendly apps—such as MAPS.ME or Wheelmap—encourage lots of new people to add data to OSM without having to learn the data model or how to check whether that data is already existing.  I often remove duplicate nodes, fix tags or fix location of objects created by users of those apps.  The more newcomers, the more we’ll have to deal with incorrect data.  These people certainly have good intentions but having a process to validate potentially incorrect changes will be necessary as the community grows.  And that will work for deliberate vandalism too.

Cheers.
Yves
