[OSM-dev] Vandalism how to proceed?

[Apollinaris Schoell]

any ideas on how to deal with vandalism of a technically skilled user?
has the block user function ever be used? how would one request it. I know I can't just call for it without evidence but can't spend much time right now for documentation and explanation. conformation from other users …
 so some info when the admins are willing to consider a block will be appreciated.
If anyone want't to check it started with this changeset of mass upgrades from residential to tertiary of approx 3500 roads

I have started to write some tools to analyze the edits and come up with a more intelligent revert of defined tags across full history only but due to time constraints this isn't finished yet. also not sure how this will help as this user can simply use revert.pl again to revert all my changes blindly as he has done multiple times.

multiple users have contacted this users but refuses to accept any other opinion, advice, discussion …
one example below.

> 
> discuss ideas on the lists first 

If I wished to discuss an idea, I might do so. However, I'm unlikely to do so on mailing lists, an outdated technology ill-suited to the task at hand.

Regardless, I have yet to be convinced that there's anything to discuss, let alone that there's a need to have a discussion first, as if I need permission. 

> but you think after a month you know all better?

Of course I think I know better. I don't purport to know all better, so I do research areas of lighter knowledge.
