I came here from looking on alturnatives to reddit on notabug. Anyhow, I was amazed when i first joined and saw this place was running reddit open source as well. Sadly, my hopes were dashed when I saw the "content policy".
Although I like the idea of somthing like a "pyramid of debate" as mentioned and holding yourself accountable to it, I really think this site is stepping into dangerous territory by making this an actually enforced rule. The reason being that this is honestly so subjective, and its really up to the individual when someone has gone too far. This also shows the issue of centralized moderation, which this site seems very ceciptable to.
Finally, the censorship of porn is frankly unnecessary. You could just do something like Notabug does and simply not host any image content (which this site already appears to do) and you are basically completely in the clear so long as you remove any reported CP links.
