That's a very "computer person" approach to take. In fact, the
"McDonald's" issue has already been tried by someone in the past with an
undiscussed mechanical edit, promptly falsifying a few non-chain
non-fastfood places that *really* were called McDonalds just as you mention.

It is also an easy fallacy to think that if the marketing people of some
chain decide to spell their name differently, we could or should simply
replace all names to what they "should" be - no we don't, we only change
the name when the store changes its lettering. We're not a parrot for
the marketing department, we observe what's on the ground.

OSM editing is usually "holistic" - you work on many aspects of the map
in an area. If the map has many edits by different people in an area
then I can reasonably assume that it has a certain minimum quality
because these people are on the ground fixing things. If you
remote-mass-fix McDonald's, or worse, if you remote-mass-fix all chain
stores on an ongoing basis, you create a false impression of activity in
an area when in fact all you do is scribble the latest business decision
of some corporate marketing department all over OSM.

I don't think that is something that really advances the quality in OSM,
and I would encourage you to grab a notepad and venture outside to do
some mapping. That way you wouldn't be scripting world-wide cleanup
operations but who knows, you might actually add real value to OSM.

Leave the mis-spelled "McDonalds" to those who map in the area. Maybe it
encourages them.

Frederik
