Okay I don't know if a fold is the best advice here, I guess so but how often are we getting bluffed in this spot?

You're never getting bluffed here, it just depends whether you think he's vbetting a worse 2pr which is pretty unlikely given that the only combination is QJ. I probably bet/fold around 11 on the river, no worse hand is raising here. EVER
