Read topics appearing in unread content feed

[Hellenion]

More and more topics I've already read are appearing in my unread content feed, what's going on?

I don't recall messing with the filter, which looks ok with "Read Status: Unread"

Might be reactions counting as content or something. 

That is odd

especially for how old those posts are, 1 or 2 of those players I believe were banned for being too young.
