Why Satoshi has created this forum ?
I agree with spam contents we cannot spread awareness of bitcoins to new people.
But we cannot expect non-native English speakers to participate into higher end discussions.
Just imagine a non-English 20 year old boy joins here and enter the general discussion board, if he finds a topic bitcoin is money or investment, he will try to say something but if he sees ONLY discussions like high technical subjects for example about segwit, he will probably close the tab and will open facebook.
In long run we may lose a possible bitcoin adopter.
If bitcoin is only for native English speaker then we can have higher standards for topics and posts.
(still I doubt they will be ready to talk for tech topics)
Obvious spammers/ copy pasters must deserve their ban. No second opinion on this.
I view this forum is doing similar role of block rewards. Those who got possibilities run mining farm and earn rewards. Those who got interest to write about cryptocurrency, join here and earn bitcoins. But we need to note here that both are just bitcoin adopters without adopters there will be no life for bitcoin system.
But recent changes seems a heavy deviation from motto of this forum.
