[OSM-talk] Request for user block

[Nakor]

   Hello,

The user osm_king (formerly n_ward) as been doing vandalism edits:
building shaped like a penis, insulting changeset comments, creating
ways in the middle of the Atlantic ...

I kindly asked him to stop and got the following answer:

"Thanks for your feedback, but you can shove it up your arsehole"

Who should I contact to have this user blocked from editing?

  Thanks in advance,

N.
