OSM ha la sua propria definizione di vandalismo, che rientra perfettamente nel tuo comportamento:
Vandalism is intentionally ignoring the consensus norms of the OpenStreetMap community about editing data.
Queste norme di consenso comprendono, ad esempio, i bilinguismi. Che hai provato a modificare più volte sia con il tuo account principale che con i sockpuppet.
Why don’t you focus on editing your own area, with on-the-ground surveys, instead of changing (and deleting!) place values and place names of territories far away from you, where those place and name values has been already been decided by local users and remained the same for +10 years? There’s much to do yet in your city. There are many cool apps to be used on the field such as StreetComplete, Vespucci and Everydoor.
Also I think a good thing from you would be to make clear which other accounts belong to you. For instance, are these accounts yours: saifanjahmal | OpenStreetMap and https://www.openstreetmap.org/user/crosley-millan ?
