Why not? You are giving villain all the choice by check/calling multiple streets because you're telling him your range just isn't strong. Thus, when villain knows this about you, if he's even half-way decent, he knows what sorts of cards are bad for you if he wants to bluff. And he gets a better idea about your range if he's inclined to v-bet thin.
Think about it this way: If you told villain you held a range of [77-99, Q8-KQ, medium flush draws] wouldn't it be easy to play against you? By check/calling multiple streets, we're making our hand range very narrow and weak/medium strength at most. And wether villain wants to v-bet or bluff, narrowing your hand range down makes his decision easier no matter what he wants to do. Obviously if he could see your cards, he'd be able to bluff us or v-bet us better, and this is a similar situation. It helps him be able to do both. Which is why check/calling multiple streets is so exploitable. When regs take that line against me its just too easy to assign them a range, and I start v-betting super thin, or bluffing super frequent depending on their tendancies, my hand, and the board.
So yeah, often I'll realize "Oh, villain has a medium strength hand (2nd pair - TPWK)". And sometimes the board will develop well for him to call me down, so I won't bluff. Or sometimes it will get scary and I will. Or sometimes I'll have a hand like top pair, 3rd kicker, and I'll just keep firing because I know I'm ahead. But either way, no matter what hand I hold, or what my goal, because my opponent has defined his hand in such an obvious way, that I can make better decisions against him.
I keep writing about this because I just hate hate hate hate hate a line of check/call, check/call, check/call. Your plan for the hand should almost never be to check/call every street without a damn good reason to do so, because its just so exploitable.
