Going to Jail for Linking? What Sen. Amy Klobuchar’s S. 978 Could Mean for You

Yes folks, The same party (Democrats) who write the bills you grow to hate about banning M-rated/Violent video games off the market want you to be in jail for stuff like commentaries, reviews and other uses of copyrighted material which fall under Fair Use and Title 17 of the U.S. Copyright laws

Lol, did you even read the whole web page? The quote at the bottom basically says,

"This is to stop the people that pirate DVDs and CDs online in the same sense that we prosecute people who do it on street corners."

You have nothing to worry about.

oh really? listen to those who are REALLY worried/pissed
YouTube - ‪Help Us Squash S. 978!‬‏
YouTube - ‪S. 978, the new "Ten Strikes" bill rant‬‏

Ooooooor you can read the article with actual legal people explaining what it means for you and not the panicing internets people.

Legality doesn't mean jack when YouTube takes the DMCA (Digital Millennium Copyright Act) seriously, DMCA is a very flawed piece of legislation and anyone can on YouTube can easily abuse it even those who disagree on your opinions (i.e. Butt hurt) can easily flag your videos even if they are considered fair use and under Title 17 of the U.S. Copyright Laws

and the fact the bill S.978 targets more than pirated DVDs is more alarming
YouTubers are in red alert over this
Why not watch their videos to understand their concern (like the ones below)?
