[OSM-talk] Duplicate nodes incorrectly removed by bot BugBuster ?

[Apollinaris Schoell]

please stop this Bot until it's usefulness is proven and others agree it
should run.
it was never discussed in this list and a bot affecting the whole planet
should be discussed first for risks.

what happens if 2 nodes are used by different ways?
merging them is creating even more problems by creating duplicate ways.
some duplicates are on purpose and might be the smaller problem in the
database.

running a bot of a planet file is a bit dangerous, there  are well know
problems with the integrity of the planet file.

again don't come up with a bot if you are not sure about side effects.
fixing duplicate nodes on an open polygon is a good idea. but fixing all
duplicate nodes isn't
