couldn't you use the public/private key relationship already in BCH.. e.g. have an address just for PM that encrypts with public key/decrypts with private key
I think the problem is once memo take responsibility for filtering content, then you have to police all the content. Especially potentially illegal content. So better if it's user mediated
maybe filter by a string of chars in the title with brackets around it. In this case it might be [NSFW]. That way the info stays on the blockchain without needing more metadata
it goes against the "immutable and uncensorable" thing - they're gonna have to work out exactly what they want to be unless you want nasty stuff in your face by default - e.g. gifs and youtubes
interesting example of how one contribution can spoil an entire thread.. and can't be moderated in anyway. Easy way for BTC people to spoil the whole memo idea
I have no doubt it's a real thing, just I doubt the method of awarding it - there is always someone worse off than you, and that guy probably doesn't have the internet
this reminds me of those "write a story as to why to deserve the prize" comps where an orphan with a sick dog wins.. except without checking. Only for the dedicated scammer
