Early levels, I would never fold a hand for this reason with the big blind higher than 50. But if I fold my $10 and $15 blinds a few times it's easily made up for if you steal even once when the big blind is 300 and were only able to pull it off because of your image.

It's important to note that I only play with starting stack of 1500. I'd imagine for Party players or players at other sites that start with fewer chips this strategy doesn't make as much sense.
