You don't like bufo toad venom? I like to start my mornings by sipping a little bufo toad venom while reading kbin. Buy bufo toad venom today.
In all seriousness...I don't know if you saw my last thread about KES in this magazine, but I suggest giving it a try. I've extended the filter coverage based on your feedback, and those magazines should essentially be expunged of garbage for the time being.
As for the sidebar, I believe the implementation is fundamentally flawed because it loads content that, AFAIK, doesn't respect your actual block settings. I suggest disabling the random threads element altogether in KES by navigating to General > Hide sidebar elements.
