I would either raise or fold PF. I lean towards folding, because a raise is only going to tie you to a pot with a marginal hand against people who are giving you a first-class ticket to showdowntown.

That said, bet the rest of the way. You have top pair against what are essentially random hands, so maximize your value (and make them think you are LAGtastic too, because what tight-passive player (or whatever they think you are) really valuebets top pair after two overs have fallen?)
