Hmm - I get an average of 1000 messages a day, mostly spam, and I have - good grief - 4000 seperate email addresses in my inbox - and it just took 0.001 s to decode a txt file

So that's 4000 seconds to prove a message is spam

I'm not loving this idea

That can't be right ...

FYI, bitmessage (https://bitmessage.org/) is a working implementation of this "Everyone Gets Everything" model. Maybe have a look at how they do things ?
