Title. I cannot upvote any comment or post. I guess there's some algo or something designed to prevent the use of alts to game upvotes, so that might be the cause? I deleted my last account, though, as I like to do so every once in a while for privacy reasons. I think I've had previous accounts that I've also deleted and others for which I forgot the password, but I haven't logged into those since, well, I forgot the password. Anyway, I haven't engaged in any behavior that could in any way be considered vote manipulation or any other malicious use of alts. In fact I've never had an actual alt, as I've only ever used one account at any given time. Yet, I still have not been able to upvote since the creation of this new account.
