Here you go, btw you can find the link if you go to any manga (not chapters) and slide down (usually it's on the right side under Similar manga section)

Yeah, I hope it will get updated quickly so we can change these weird-ass letter pfps.

Nope, unless bot changes mind it won't be temporary but it will get updated. So, basically this is just experimental version.

It's not temporary unless bot changes mind. When Disqus has stopped working two days ago, I think bot got fed up with it and made this. From what bot said there will be updates to pfps and other features, and maybe in future we might be able to link these accounts with disqus ones in someway.

Not yet, it's already planned tho.

At least the old comments still do exist in someway and didn't get completely wiped out.
