Steve,
Thanks for your thoughts, and I hope others in the community
will share their views. My view would be that it should be OK to do
such a reverse if the person has not signed the new license,
particularly when there has been such an enormous number of questionable edits.
If it is decided to do reversals, I suggest we start with
his most recent changesets and work backward, little by little.
Though most of his "edits" follow a definite pattern, a few appear to
be unique, genuine edits much like the work we all do. I'll bet the
most recent work is what was done robotically.
Also, to give a little more information, many of the "edits"
often show up as intersections that must be deleted and redrawn. This
is a particularly time-consuming process, as, I believe, "blars" knew.

I have been working on the LA remap, which mostly involves

The odd thing about the "edits" that "blars" did is that
they seem to have been done almost robotically. Although many
intersections have been changed enough to be marked "modified" by
the OSM Inspector, it's difficul to see what, if anything, was
done. The poor street alignments from TIGER have not been
corrected. Obvious issues, such as a street that no longer exists,
have been ignored. Almost every single dead-end street or those
with turning circles are "modified," as are many intersections,
but, again, bad alignment has not been touched.
All this plus the sheer volume of changes makes me think
that "blars" used some kind of bot to make these changes. These
"edits" corrected or added little, except to make the map
"modified" for the new license.
Perhaps someone who knows JOSM or other tools better than
I do could come up with a way to make these repairs on a mass
basis. Or, perhaps, there is a wasy to reverse just what blars did
within a certain time frame.
I appreciate any help you can give. I've put in hundreds
of hours on this and barely scratched the surface.
Hello Charlotte:
I have been watching the fine efforts in greater LA, with impressive
progress and results (in a "slow and steady" way), so I first wanted
to congratulate you on your efforts, and especially reaching out to
this talk group. You have done much more than scratch the surface,
you (and others) are making real progress.
One method may be to revert changesets by blars. Reverting
changesets can be controversial (it is polite to ask / reach
consensus with the original author, et cetera). However, in the
case of an editor who has not agreed to the new CT, it may be
correct for OSM users who HAVE agreed to the new CT to establish
if/when/how this is an OK/proper thing to do. And then feel OK
doing it, and then do it.
Technically, reverting a changeset is rather easily done with a JOSM
plug-in, which you can read about on OSM's wiki. There is the
separate issue of IDENTIFYING which changeset to revert, which can
be "more difficult" and then there is the rather straightforward
procedure for doing it, which isn't difficult.
But "socially," or more properly stated, in the context of "reaching
OSM consensus," what does our community think of (rather wholesale)
reverts of a contributor who has not agreed to the CT? Are we OK
with that? Apologies if this is already clearly stated somewhere.
But if so, I haven't seen it and it is high time we freshen up
how/where we are about this.
