I could go either way, but I don’t think “other platforms have public voting” doesn’t seem all that convincing. Who cares? I don’t care who voted on what, and I doubt most others do either.
While there are workarounds, leaving it as is at least weeds out the majority of trolls who aren’t technically inclined enough to go pull up A to see how B voted on C.
Imagine the disaster we could’ve averted if they hadn’t shot Harambe.
