Pewdiepie has disabled comments in response to this terror mistake by Google, until they are fixed.
"Turning comments off until they are working properly.
Due to the recent changes of the YouTube comment system I'm forced to disable comments.
Since front page/top comments are filled with: Links to virus sites, Advertisers, Self Advertisers, Spam, Copy and paste pics of dogs (I'm ok with those though)

... Anyway, the list goes on.
Sorry about this, it's not an easy decision since I love reading your comments! But I hope this will get fixed soon, my proposal would be to let us disable top comments (as we could before).
Until then I'll still reply on Fb and Pm's

Since he's the most subscribed channel, and veeeeeeeeery iconic, I bet they'll probably listen to him, because they'd never break his partnership.
Nerdcubed (1.3m+ subs) is also doing the same thing.
THIS COULD BE A REVOLUTION
