Spam Removal (removing spammy description tags from legitimate businesses; remove businesses altogether if they have only description, name, payment methods etc. but no tag that says what business it is. Keep address node/building where useful.)

    Hi woodpeck, would you mind to create smaller CS? It's impossible to use achavi (etc.) to have a closer look what you've changed. Would be really great!
    Second, an example: I don't get why you deleted description=... @ https://www.openstreetmap.org/node/4144996689. It included useful information for proper OSM-tagging - now it's gone. Just an example.
    Was there any discussion prior to your changes?

    My changes are really just to individual objects so they are immediately obvious from the object history or from the deep diff tool here http://osm.mapki.com/history/node.php?id=4144996689. I have about 1000 more to go, the overwhelming majority are in the US, maybe I can split them out and separate continents. I agree that the node you have singled out is a corner case - most descriptions I delete are pure and outright advertising ("we provide the best of this and that" etc.) whereas in this particular case it was just a list of services provided and not a slogan. Also while most descriptions I remove bear clear signs of having been added by SEO companies, this one was likely added by the owners themselves. I'll reinstate that one. I have generally removed spammy descriptions even if they bore some valuable information because I thought it is not our job at OSM to improve what SEO companies cannot be bothered to do right!

    Thanks for your quick response!
    Splitting the uploaded data into to big pieces like contients won't help "average" mappers doing QA, I believe. The easiest and well-established tool, achavi, will fail.

    Your changes here: I do agree that pure advertising shouldn't be part of OSM and can be deleted (thanks for your efforts by the way!). But I think it would be better to not just kill one "line" (description), but to check the whole data of that node or even CS. There are two other examples from Berlin/Germany (the only nodes I checked here):
    1) n2331627861 -> opening_hours correct? should be improved; website (http(s) missing)) -> ok, minor stuff. Now take a look at the only second CS by that user and the node created. Compare it with the description you just deleted in n2331627861: https://www.openstreetmap.org/node/3479075185 -> note=* :-D :-D

    2) n4890004753 -> what about those strange asterisks? (website (http(s) missing)) -> ok, minor problems. Nice, if they were solved, too.

    I do understand and support your basic idea, but in my opinion it's often better to take a closer look at all the tags of one node + CS + in some cases even the user and other CS by him (especially if it's obviously an ad-user like '030daten'). Quite a lot of work, yeah. But it's often the same: if an user is aware of what he's adding to OSM (here: ad's in description), he's probably adding some more ad's (maybe he's even not aware that OSM is not welcoming that kind of data).
    No offense :), see ya
