Why Satoshi has created this forum ?
To talk about bitcoin, hence the name bitcointalk.
But we cannot expect non-native English speakers to participate into higher end discussions.
Why not? Many non-English speakers participate in substantial 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 page.
Well maybe he is better wasting his time on Facebook then. This forum doesn't exist just so non-English speaking members can easily earn money by saying "yes bitcoin is money" rather than actually having to put any thought or meaning into their posts.
In long run we may lose a possible bitcoin adopter.
No, we wont. We'll lose a forum poster. One that wont be missed. This forum is not the entire bitcoin ecosystem; it's a tiny part of it.
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)
Bitcoin isn't just for native English speakers, but this forum is an English-only speaking one (with the exception of the local boards (which is where you should stick to if you have trouble with English)).
But recent changes seems a heavy deviation from motto of this forum.
Translation:
My alt(s?) was kicked off a campaign and I'm upset about it? How many more threads are we going to get by butthurt sig spammers who are annoyed that they can't easily earn money any more by posting unsubstantial rubbish? It's letting people get away with having ten alt accounts posting the same illiterate nonsense account after account that has lead to the decline in quality of the forum in the first place. It shouldn't and can't continue and that's why certain people are trying to do something about it. The only other option is to ban campaigns entirely from the forum, but if they were you would be screwed anyway, but why should those people who don't spam be punished because of the others?
