I concur with the view that bad imports hurt OSM.
I'd like to make a few pragmatic suggestions to reduce imports.
First, I think the most important thing we as a community can do to
reduce bot/import issues is to identify them.
I personally use OWL to monitor the area around where I live and I
make a cursory check of the changes in my area. I think most serious
mappers should consider doing the same, just to keep up to date with
what's happening in their area.
One could certainly write a script to help identify bots. Tell-tale
signs might include large bounding boxes, large numbers of changesets
in succession, lots of the same types of changes, etc.
Next, I'd suggest we reduce the number of changes per changeset. While
doing this might make bot detection harder, the upside might be easier
Then we should require bots to be registered- a "bot account" would
have reduced restrictions on it, but would be more heavily
scrutinised, if by no one else, then by the community at large.
None of these, with the exception of the bot detection, would require
any new software.
