Hi, jhaluska80! 
My name is Kate, and I’m a mapper on the OSM team at Lyft. 
While working on the project, we received data that the certain tags which are important for routing have been changed recently. According to our workflow, we monitor edits with these tags in order to quickly identify and eliminate potentially incorrect and vandalized edits in OSM. We only make changes if we have sufficient evidence to justify fixing errors.
