Google Wants You to Use Your Real Name on YouTube
Google has launched a pop-up dialogue box on YouTube that urges you to use your real name when trying to make a comment. From the article: "When you try to comment on a YouTube video, a box will pop up that displays your username as it’s currently seen, along with a side-by-side comparison to what it will look like if you let YouTube pull your name from Google+. You can choose 'I don’t want to use my real name,' but that will lead to another dialogue box that basically guilts you into agreeing. If you still insist on remaining anonymous, you have to tell Google why: 'My channel is for a show or character' or 'My channel name is well-known for other reasons' are two options. 'I want to remain anonymous, is–unsurprisingly–not one."
you have no legitimate reason
It's nice to know you have the ability to define what is and is not a "legitimate reason" for everyone.
But of course, there is another choice that you did not present: continue posting anonymously.
Filthy, filthy copyrapists!
