Having an LN paywall on the relay recreates the problem I was trying to avoid… I’m not sure it’s legal to require payment to report content problems. e.g. a copyright holder shouldn’t have to pay someone who’s violating their copyright. But PoW isn’t payment, which is why that might work.
But then there the problem that PoW is really slow in browsers (see screenshot below). It can’t take a full minute for browser-based users but be instantaneous for bots on servers. That makes no sense.
