I never found it unethical when a few players at my local cardroom throw their hand away instead of checking. I find it hilarious when they do it on a constant basis.

Folding a big pot for one bet can be a big mistake even with a weak holding, but folding for zero bets? If you do it once for a specific reason that's one thing, I'm talking about players that do it several times an hour.
