actually yes I do have more.
I found out today, that a specific rank that I had set up a private forum section for was using that to break the feed for everyone else on the website except for them.
They would post a message into their Forum and quickly sign-out. Which would cause the Activity Feed to not load newer content for everyone else, while it would load for them.
That forum has since been deleted and I didn't try to "break" the feed like they had described in one of their post.
