Attention was drawn to the OSM user RR8 last night on IRC. It appears
that they have been producing /apparently/ deconstructive edits at a
high frequency since late Saturday evening (server time).
Edits primarily are the reclassification of highways to a different
level. This has occured frequently in the East Midlands (often
including a change of reference number that cannot be confirmed from
other sources), places in Ireland where under-construction motorways
have been marked as opened, and a few reclassifications elsewhere,
most notably Iceland.
The edits appear to look constructive, but are more likely to be
destructive. Ideally, someone local to the areas in question should
check a few of the changes, or we could get people from the mailing
list to consider the edits as a whole to decide what's to be done
