Just an observation that I am wondering whether anybody else is seeing.
I am in the UK and most mornings my first point of call on the internet is EE. Check out what's happened overnight, see what I have missed from the other side of the pond with them being 5-8 hours behind.
More often than not, my feed is littered with Posts containing advertising and I have made several reports to Moderators.
For example, this morning, feed contains (in order from top to bottom) a question from one of my topics, official advert post, non-official advert post, another non-official advert post, a post that should have been a question, another question; I have now scrolled down to at least the third screen's worth of entries and I am now getting to see the questions from my topics; assuming they have featured in my feed as I don't always see all questions from my topics (bug request already raised).
