Technically you were supposed to be looking up the research for anything that mattered to begin with. I don't usually trust wikipedia for anything that i'm going to have to talk about later. The sources are for that.
That is not a fault to Wikipedia. That is on you.
There was a post on this yesterday.
They are moderating something, the issue with the article was it's not user's bookmarks. It's some app-specific feature called collections.
edit: it's the same post...it's a bit weird linking a direct link to a lemee.ee post when they get federated here anyway.....
