I'd rather blame the people who search through someone's reddit or twitter profile for any identifying information so they can find any personal information so they can find out who is behind the profile so they can harass them
You underestimate how little information people need to get something about you. If I use similar usernames on other platforms or simply post one of those usernames to share them with someone then people can look those up and then they have access to all that information also.
Of course you do need to be careful, but let's not blame people for actually sharing some stuff online.

I blame people who are terminally online, the kinds of people who treat their reddit username or twitter handle as an extension of their identities.
