[Mailman] Accidental Upload of Destroyed Data

[Jono Saad]

Hi there,

I hope this information is being sent to the right place and that I will be able to get this issue resolved.
I have been working on a project where I need to re-design a few maps in my local area. I needed to hide unnecessary information and make a few small adjustments.
I am completely new to JOSM software and have an very limited understanding of how it functions and the purpose behind OSM.
My aim was to have a locally stored OSM map that contained the necessary changes, but I accidentally hit "Perform Actions Before Exiting" and uploaded these changes online.
It appears that I have deleted a large portion of residential points, POI and Bus stops from the map, among other things. The area affected is within a few areas of western Sydney NSW.
I have read on the Wiki about reverting deleted changes, however I am to inexperienced to understand how to revert these changes.
Would you be able to help me to make these changes as I have no intention of destroying other people's work.
Also, could you recommend the best way to make personalized maps using OSM?
I apologize for any inconvenience that I may have caused.

Kind Regards,

Jonathan Saad
