Once it's fully locked in it will activate later on in August (I forget the exact date but it's middle to end of August). Once it activates there is no turning back, but it has to be locked in before Aug 1 to avoid the UASF. So BIP148 (UASF) won't try to take over if BIP91 is locked in. We know for sure we're out of the danger zone once SegWit is actually active mid Aug. From now till then it's just more uncertainty. The first hurdle to overcome is reaching 80% signalling of BIP91.

I don't think you can blacklist the bitcoin protocol. You can theoretically block the ports it uses, but you can always just get around such measures. Also why would anyone care to attack bitcoin like that. If it all becomes a clusterfuck the media and all the other altcoins will just point fingers at us and laugh. Shitcoiners be like "Who's the shitcoin now! Ha!"

Heheh, I guess by the negative sentiment against PoW change you are a fellow miner!

This is pure speculation but I don't think Bitcoin ABC will be "the chain of value" - quite the opposite. It will be the Polit Bureau Coin (PBC Coin - pun intended), centralized and controlled by the mini bitcoin dictator wannabees
