There is a cursed YouTube video!!!

[poiihy]

I clicked on this video but when it played it showed up glitchy so I reloaded the page but it was stuck and wouldn't reload and I couldn't load any other pages and my system was laggy and my clock and cursor were freezing/lagging repeatedly... so I put the machine to sleep and woke it back up and that solved the problem. So then I loaded the video again and the same thing happened but worse! System froze up completely including the clock and the cursor was sometimes lagging (cursor moves fine then moves laggy then fine etc). So I had to kill it and reboot. Then I tried a different video which worked fine so I tried this video again and IT HAPPENED AGAIN! So had to kill and reboot again but now my hard disk drive sounds different! It makes louder ticking sounds when seeking. WTF?!
This happened with Safari 9.1.2 in El Capitan 10.11.6 on a Mid-2009 MBP.

Here is the link to the cursed video:

Are you using Adobe Flash or HTML 5 to view the video? If you are using HTML 5, I have a similar problem, and it's happening with a bunch of HTML 5 applications. The system goes idle, the clock stops, the keyboard is locked out, and there's no choice except to do a hard reboot. Switching back to Adobe Flash fixes the trouble. What I don't understand is how something running inside a user application is able to lock out the operating system. The OS should detect the problem and kill the offending application.
