This sometimes also causes problems for the authorities themselves for a change.
I recall some TV program long ago mentioning the police had trouble with Russians because sometimes they think there's a whole gang and it's really just one guy whose name got corrupted in 5 different ways.
Depending on the Russian name and the local language there can be many ways to screw things up. Like Elena might get written down as Helen somewhere and Lena somewhere else. And that's just for viable normal names.
It's not even necessarily corruption; we address each other by different names depending on context.
To acquaintances, I might be a Pavel; to close friends, I might be Pasha. To my mom, I'm Pavlik. In a business or other more formal setting, I would be Pavel Dmitrievich.
I think it's a common complaint when reading Russian novels, non-Russians get confused about who's who because of these types of shifts. And it totally makes sense; at least my various nicknames start with the same letter, but many Russian "short" names don't particularly resemble the full name. Who would expect Aleksandr to be Sasha, if you didn't grow up in the culture?
There was a hilarious one in Ireland where we were desperatly searching for a prolific polish criminal named "Prawo Jazdy". Which means... driving license.
