If the author can use the Google Maps feedback tool to get the errors fixed, I'm pretty sure somewhere on the internet someone with malice can also use the same feedback tool to place the address at the wrong location. The only safeguard is probably a low-paid contractor in India reviewing these manual suggestions.
Someone did this a couple of years ago for a major thoroughfare near where I lived. They marked it as one way for a key stretch, and traffic ended up being re-routed down much smaller roads to avoid it. It caused all sorts of chaos, both due to the increased traffic on roads not made for it, and in the long queues that formed where the traffic then rejoined the thoroughfare.
It took google at least the best part of a month to fix it (at least, it was around a month from when I submitted the correction, no idea if others beat me to it)
One year ago the Elizabeth line disappeared from the maps in London. There are many Reddit posts about this such as https://www.reddit.com/r/LondonUnderground/comments/1be01n3/... and https://www.reddit.com/r/LondonUnderground/comments/1b0xxb0/.... I asked a friend who worked at Google and they said that it was because some poor workers in India accidentally hid it while fixing something else.
