While reverts are in progress, do not edit affected names
To redraw the map in the browser after rollbacks, reload the page without cache: Ctrl+F5 or Cmd+Shift+R.
If you notice new cases: go to user profile → Report this User
Also at the link you can also see that we reported the current status of reverts and explained how it works, why vandalism may not disappear from the map for a long time.
HDYC and OSMCha (if I remember correctly because Overpass was unavailable) became victims of such diffs in the past times. Live-update users in OsmAnd also faced huge updates.
Also, edits with 10k modified objects are very difficult to view quickly and without lags in the change viewer. OSMCha, Achavi, JOSM.
And imagine vandalising not just one person, but several hundred organised on some 4chan or on a video blogger’s stream
By the way, code is already deployed for testing here: https://tomh.apis.dev.openstreetmap.org/
You need to sign up there (your main osm.org account won’t work there), and then try uploading some, or even lots of data.
you can test whether reasonable edits are going through and mass scale vandalism is limited (and error handling in editors and API and so on)
We’'ll have a look. Blocked for now, we’ll amend that message with more detail once more detail is know.
At first glance it looks like a case of password-stuffing; and if so it wouldn’t be the first example in OSM. The general advice to avoid this sort of thing is for people to ensure that they don’t share passwords between accounts for different things on the internet (so that if passwords for site A get published, they aren’t useful for site B).
large-scale vandal activity should be now reduced, as large edit volume will be blocked, especially from fresh accounts
note that large scale edits from new accounts may be also affected, but should not affect vast majority of genuine new users
brand new bot/import accounts may need to operate in way dealing with rate limits if editing at huge volume, also old ones may be affected if volume is exceptionally large
Thanks for everyone who contributed!
Note that further changes may be needed to make life harder for vandals. For example abusive use of delete account feature likely should be stopped/reduced.
… and now reverted (by several people, including me in this changeset).
Because there have been several people reverting things at the same time, it’d be really helpful if people could see if there are any examples of problem data still existing?
With the latest vandalism in mind:
Wouldn’t it be a good idea to also limit the changesets of new accounts in size (area)?
This would make it slightly more difficult to make global vandalism resulting in this massive tile updates we saw the last week.
