It takes effort and knowledge to make good contributions, this app is just a tool to do that.

I can only say I myself try to make valuable contributions, some other people might care less.

I think EveryDoor requires some relatively deep understanding of OSM before actually being a useful tool. So edits like this should be rare with that tool. Many of the edits like this are from when MapsMe was very popular and suddenly introduced editing, without enough nuance in the process. Bad edits do happen everywhere, you need a good balance between people who data curation and newbies making beginner mistakes. In some places, there's a lack of experienced people maintaining the data.
