OK. But here there was no need for an immediate action. The nodes I deleted did not provide more info than that there is an ATM. In OSMand~ for example when you search for an ATM, you get results in both cases (separate ATM or atm=yes).
So there is time to give people a chance to discuss.
When you give people a chance to discuss, they can and will learn and not become discouraged.
Here in Albania we miss active members and one of the reasons are that there are few persons, who even no longer live here but still map and make immediate decisions/actions.
Back to my case, your argumentation made sense, i could have said "I agree", the other person in that discussion sees that too and I could re-add the ATMs on my own.
