50NL: Am I getting taken to Valuetown?

[RunDownHouse]

Villain appears to be TAG so far, with a twist. He loves floating me. He's done it once an orbit or so. Maybe he thinks I'm FOS, since I've been getting hit by the deck and thus raising pf a lot. Every other time he's folded to my cbet. Once, I opened from the button after a fish limped, he 3bet from the SB, I flat call. Flop is rags, he leads for about the pot, I come over the top, he folds. Other than that, its been him calling my opens in position or from the blinds, and then folding.

Did I induce a bluff here, or is this pure value bet? Is he maybe valuebetting a worse hand?
