Now for the most controversial option—locking your Tweets. Unless you're a minor (in which case I'm not sure you should be on Twitter at all), don't. It's the Twitter equivalent of walking into a room and asking everyone else who's already there to put on earplugs while you talk to the 3 people you like the most. Mostly it just makes you look like you don't understand Twitter. If someone's a bore, or a spammer, or a creep, block them. Assume everyone else is just another nice person like yourself looking for a new outlet to reach whatever goal they selected.
