[Talk-de] unusual cluster of German accounts

[Richard Weait]

Hi All,

I've found a cluster of accounts that mapped in Germany.  This cluster
seems unusual to me.

There are nine accounts.
They all contributed only for one day.
They all mapped in places in Germany.
They all contributed a large number of changesets (on their first day
of mapping).
Each account uses similar changeset comments in German and English.
None of the accounts has responded with respect to CT/ODbL.

Looking further into the activity of these accounts, they each appear
to make a test edit, followed later by larger edits.

I don't know what to make of the seeming shared behaviour other than
to say that it seems unusual.  Could mappers in the effected areas
have a look at the contributions and offer opinions?  If these account
have not been contacted w.r.t. CT/ODbL, perhaps they will all agree at
the same time?

List of unusual accounts with some similarity graphs.
