or at least mark it as disused.
I know it's not the remit of OSM, but it's fun for me to navigate through an area in an editor, stumble across points that bear no resemblance to the background reality, thereby at least learning a bit of the history, imagining life in the past, and best of all, taking a break from mapping to research the POI, learn its history and importance (destroyed by fire? flood? oh neat) and perhaps more about the area and its history. But best of all, being distracted from mapping for a few hours.

Hello, The Vandal Formerly Known As Juggalo Kyle,
I see you have changed your username, and are continuing to delete the same items that have caused you to receive a temporary block from the Data Working Group.
Note that what you are doing, by removing valid data from OSM, is considered vandalism.
I suggest you consider that, while others continue to restore the data they find to be useful and valuable.

Hi Mateusz,
are you aware that the NE2 account is placed under an indefinite block, and is highly unlikely to respond?
Just thought I'd point that out, as somehow seeing this username in your comments made me have to check that out...

A better philosophy for you to grasp is, OpenStreetMap documents the world as it exists.
We do not map for the app, we map reality.
We map landuse.
These are school grounds, and that is fact.
If these facts bother you, take it up with your app, it is not for OSM to pander to the apps or their users who are affected by ground-truth.
Please leave the map alone for the thousands of other data consumers who increasingly rely on OSM to have correct, up-to-date, and comprehensive information, not fiction tailored for one particular app.
Your deletions will be reverted.

Hi mysterytheatregf,
One very helpful tip I can give you to make your map editing much better is to use a different background image.
In your area, and for that matter, the entire state of Connecticut is covered by highly-detailed aerial imagery with I believe 10cm resolution, far better than what you use.
This is available as ESRI World Imagery or similar. The details of how you select that in your editor I cannot say (perhaps change background).
With this you can zoom in two additional steps to zoomlevel 21, so that a building can occupy your entire screen.
Then you can see far more detail (I believe 16 times linearly) than in the Bing default background, and you can trace things much more precisely.
.
That alone would help you avoid the problem of a house and a garage and a pool ending connected -- I separated the pool and made it match the background as a proper rectangle, but that was not a trivial task; Constable had less patience to correct the joined buildings, when it is easier to delete them and redraw them from a better background.
.
Keep in mind this is not the Pokemon map, it is a general OpenStreetMap map used by thousands of applications, as well as numerous professional businesses, emergency services, and your Pokemon is but one, and the only one for which having absolutely correct data is not the ultimate goal.
.
And this is why I gave the correct tagging of a pool to all the items you had called lakes, as well as better positioned them.
Drawing a cornfield first as a woods, then changing that to be a park, is fake data, which we do not accept because it is clear that it is an agricultural field.
In short, work on mapping carefully (I still have room for improvement) and always map reality correctly, and we will welcome your participation.
thanks!

Hi,
I just noticed you deleted this small park you had added, just as I was researching it.
All evidence I find shows me that it does exist, but probably does not have this name, officially.
I know there is a lot of controversy now over small parks like this, and I am still trying to find more references to it.
Can you explain why you deleted it from OpenStreetMap?
thanks!

ciao constable,
it looks real -- ESRI very dark imagery.
drawn from lousy bing and not accurately following the backyard outlines, I can see how you would not recognise it.
I'll try editing it and adding detail to make it more clear and accurate

offset appears far less, after drawing a new building, shifting it for skewed perspective, then comparing USGS, ESRI (old Bing) was less than a metre. New Bing z19 is far worse, many metres off, as we all know.
I hates editor crashes, time to buy a Real Computer™

Hi again!
Great to see that you are continuing to contribute and improving your previous additions!
Just thought I would say thanks again.
(And to date meself, say Greetings to Notlob ;-)

greengrocer's apostrophe detected.

I do not see a problem now, it is likely you were seeing some old map tiles not updated yet, or perhaps cached by your browser.

Confirmed, you beat me to it.
Back home from school.
Off with the kid gloves, I suggest...

thnks
this is likely redundant, but

bare rock at 168m is not borne out in the least by the aerial imagery; see my other comment calling into doubt a 120 metre elevation difference here in less than 100 metre horizontal displacement
