I was having some discussions with
elfkat about people copying and pasting from her blog and using her words as their own. The online rules for such things - particularly on blogs - are difficult. and any expectation of real security or protection for copy/paste word thievery is very old-world thinking.
I have added javascript to sites before that prevent right clicking or mouse-clicking at all. (

Even putting a Copyright (© 2010
lowfatmuffin) statement is dangerous unless you actually HAVE the copyright. (because then when you point the finger and say 'I had a copyright statement' but don't actually HAVE it - then you look like a putz.
I have a couple of suggestions. for posts for stuff you don't want people borrowing or taking - post it as a text image from Photoshop or even paint and WATERMARK it.
for example:

or even better consider writing it in word and publishing as a PDF with watermarks and link from there -

its a tough world out there - and with Google finding every mention of anything on the web - for those of us that make a living using words; its a tough reality that cut and paste can be a simultaneously cool and uncool thing.
