There was a GSoC project about a "report" button two years ago, wasn't it?

No! We are not the German Wikipedia. Users should only be blocked after
two humans verified that a user block is reasonable. Don't do
overblocking. Most of the overblocked users won't try to lift their block.

That's a desing problem of osm.org. The website is too much focussed on
the map. The full opposite is openstreetmap.de (only available in German
and needs some care) which highlights that OSM is a collection of
projects, not a map.

Your list contains only DWG members. There is a handful of mappers who
also clean up bad edits and work as an unorganized protection shield of
DWG, i.e. they comment and clean and only contact the DWG if they need a
user block. Some of them use dedicated revert accounts:


Btw, using a revert account like I do it, is a good idea. It keeps your
statistics clean.

Best regards
