Ctrl-C and Ctrl-V actually don’t work.
I always laugh when people reply to plugins like this scoffing at their ineffectiveness. Everybody knows the limitations of them, but if someone wants to eliminate 40 per cent of plagiarism, let him — and if you think that’s stupid, don’t download it.
Some sites charge for content, and if that content gets copied and pasted on blogs and message boards all over the Internet, it undermines what those sites are trying to accomplish. Again, cutting out 40 per cent, or 20 per cent, or whatever per cent, is better than nothing for the people in these situations.
I also think it’s humorous for people to assume that the general user actually knows how to work around this. The general Internet user actually doesn’t know what the heck “view source” means — and if they got that far, they wouldn’t know what to do with it.
Just because you know how to install WordPress and know how to circumvent a plugin like this doesn’t mean everybody does. It is what it is, and it’s useful for some people. That’s why it’s a great plugin. People who want it, get it. People who don’t, don’t. And some, like you, take the time to mock it publicly.
