Exactly. I'm surprised by the downvotes because, while it is not mandatory (yet?), I have definitely seen financial institution forms with an optional field for social media accounts.
People will downvote you for any number of reasons - some good, mostly bad. Ignore it, don't comment on it - "Please don't comment about the voting on comments. It never does any good, and it makes boring reading." Inquisitive and thoughtful HN readers will read your comment anyway, think about it, and comment on it.
