You giving too much importance to this forum. Banning spammers might just help this forum to be readable better, but it can not have much impact on preventing broking Bitcoin into hundreds of altcoins via hardforks... The reason is it is not so easy to have two chains sustainable longterm, you need good support from people for both chains so these can exist longterm, otherwise one chain simply gets forgotten after some time no matter if someone continues mining it.
Ok lets just agree to disagree for now, and watch what happens to ETH and ETC, it is a live example of this situation.
And we shall see then who is right and who is wrong.
