Fair enough. I see it as pretty harmless but I can see how that could piss people off and it should stop if people ask it to, especially considering it says in their first ever post to go the post and write "stop" (much like text messages you can opt out of) and if it's still doing it after people do that, that's not right considering it even tells you to do that (and it should also tell people that in its comments).

Do you have any idea why it now costs more to upvote comments as opposed to posts?
