did the algorithm of which posts get to hot got changed?

i remember about a month ago posts that got more downvotes than upvotes but a pretty high traction still managed to get to hot. now i see no post that managed to get to hot with more downvotes than upvotes, did anything change? and if so, shouldn't hot be more about traction and less about approval?
