Hello,
Paradoxically, using a new account prevents the user "franjaragon", "belmontesj" or any of their multiple accounts from getting into an edit war. I have no problem saying that my username is "Jordi MF". That user is continually watching to see if we reverse his bad edits with our regular account. I thought it was a good way to slowly "put out the fires."
I share a praise to the forum about the vandalism carried out by that user for years (https://community.openstreetmap.org/t/usuarios-editando-en-espana-bajo-sospecha-vandalismo-malas-practicas-y-otros/2510) and another more current one on the naming of elements in some municipalities in Spain (https://community.openstreetmap.org/t/nombres-de-museos-e-instalaciones-en-el-municipio-de-mequinenza/113838).
Greetings,
Jordi MF
