I think the shitbox is a really shit idea. There are great shitposting forums out there that focus on that entirely. This forum is about Automation and to a lesser extent about cars and what surrounds them. An off-topic shitbox is entirely meaningless (and yes, I get that this is the purpose of it) and only creates meaningless work for the moderators.
Either funnel your profound boredom into something more creative / constructive, or do it elsewhere.
