I am still confused about the "negativity" issue and why those negative posts are viewed as attention-getters.
That's because there is no way to know which is genuine and which is attention-seeking. While attention-seeking in itself is not bad, the overall number of such topics would quickly push out everything else out of the section if we don't stop it. We've been trying to "throttle" it somewhat, but it's not a good solution. A solid system would be better.
This is not an internet version of Stepford, where everything is rose-colored and happy.
We already discussed it. It's about the volume, or the amount of negativity, which we can't keep in check.
