Francis perfectly sums up the problems with the new YouTube comments section. He accepts the Google+ integration, but there are issues coming from that...
1) Character limit, people are posting novel length comments, and tons of ASCII Art, much of it offensive.
2) Unlimited novelty accounts like Hitler and Jesus Christ. Often posting offensive material.
3) How the top comment section works. Previously it had to be voted up, now attention getting comments rise to the top. Somebody posts something negative, people reply calling them out, that comment then rises to the top, rather than a comment that people liked.
4) External links, often to screamers, viruses and porn.
To fix those issues, he, and many other YouTube people, are going to disable comments to stop the spread of viruses on their channels, and to remove the offensive material.
An aside, I like the theory of Google+, but the fact that I can't order posts by post order (date/time order) on the app versions make it impossible to use... not even an option... At least Facebook gives an option to sort by "Top Stories" (which is never accurate) or Most Recent... The same problem is rising in YouTube comments.
