folding trip aces on flop?

[bsball8806]

Been here about 10 minutes, no stats on villain but he seems to be lag to me. Min raises a lot, limps in quite a few hands with garbage (K8, etc)

Hero is at seat 0 with $9.30. (in BB)
abercheese70 is at seat 1 with $14.26.
nandaro is at seat 2 with $4.36.
pidanys is at seat 3 with $13.67.
AndrewJH84 is at seat 4 with $10.15.
BDSMer is at seat 5 with $8.36.

Dealt to Hero: A [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img]

Preflop: pidanys calls, Andrew JH84 calls, Hero checks.

Flop ($0.30): A [img]/images/graemlins/heart.gif[/img] A [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/spade.gif[/img]
AndrewJH84 checks, Hero bets $0.25, pidanys raises to $0.50, AndrewJH84 folds, Hero raises to $2.75, pidanys raises to $6.00

Hero....?
Against most people I see this as an easy fold, but he is such a donk I can't really tell.
