I didn't make the claim Jihan was spamming, you made the claim Blockstream was spamming, but lets face it you can't prove it. So if you can't prove it move on and don't make baseless accusations.
Its weakens the rest of your argument and makes you look silly.
i said twice and now a third time, check the stats of the june 2016 and november 2016 bips dates and the mempool/ spam attacks of those times which are what blockstream needed to scare people into adopting said bips
its not my fault that you may not know where to research
many think if things are spoonfed too much it cant be believed, so its much better if you really want to know the truth, that you do your own research so that you come to your own conclusion
the data exists. go seek it out
as for "what harm can bch do to bitcoin...
its an altcoin.. it can have many many exohash of hashpower or just 1 gigahash of hash power. neither influences bitcoin because .. THEY ARE ON SEPARATE NETWORKS!!
the only REAL influence is the merchant services.. if they moved away from accepting btc and instead only accept bch.. then things matter. until then an alt is just an alt
