In terms of controlling for trolls/spam, etc annotation service providers will need to use the same combination of automatic filtering and editorial or community moderation that are relied on widely elsewhere. The success of any individual service will presumably at least partly depend on how good of a job they do.

Ultimately annotation is something that readers choose to enable by adding to their browser, and by choosing the service they prefer-- just as they may elect to have a discussion about the page on reddit, twitter, facebook, etc.

With regard to whether sites should be able to have editorial privileges on their own domain, or to what degree should page owners have consent over annotation, we've blogged about that here: https://hypothes.is/blog/involving-page-owners-in-annotation...

There's a wide diversity of opinion. Some suggested a flag where site owners could register their preference not to be annotated. Overriding that flag would invite additional scrutiny from moderators. Others have suggested that such a flag not be able to be overridden.

We also facilitated a panel discussion on this discussion at our last I Annotate conference in 2016. https://www.youtube.com/watch?v=i2yFnu_pCGI&list=PLmuJEyeapl...
