depends on the player... some players some boards going 5 bets would be -EV other players or boards not so

shoot some examples Id say, itd probably be a more productive discussion

3 bet bluffing the river is somethin i rarely rarely do and probably never in HU where no one raise folds the river and everyone raise calls (depends I guess) 4betting the river on a bluff is not somethin ive ever done

the example theoretically has come up before of huge pot both players know eadh has nothing... the answer comes back if both are good they will call with the range of K Q hi hands instead of bluff reraising so going off for tons of bets in this scenarios would be sub optimal by both players
