There's never any safeguards regarding your images being pirated when posted on the internet.
I use both watermarks & copyright text if sending out a full size file images either via e-mail or for print use, but I don't see the need when posting to websites, gallerys etc... as the low res scaled down versions needed on these sites render the image virtually usesless for comercial purposes.
As Stu quite correctly points out, if the image quality is good you just dont notice the copyright mark anyway, its a real shame as photographers we have to think this way about others, but as Digi quite rightly states its a sign of the times.
