Donk betting

[crushednuts]

I have been playing alot of 10NL this weekend and I noticed a trend that REALLY started getting on my nerves. about 70% of the time I made a raise PF in position a limper would call and then donk bet about a third of the pot into me on the flop. This leaves me wondering what to do for example if I have AQo and the flop is T62 rainbow and I whiff completely or if i raised w/ 77 and the flop was QJ5. I tried raising these light bets and was called down several times to be shown middle pair or a small pocket pair or an occasional really good hand. I am also wondering whether I should Raise or simply call these donk bets if I hit a strong hand like TPTK.

I was hoping to get a little insight into what others do in these types of situations as I seem to get donk bet mercilessly.
