Another thank you Lauda: If only more people took the time to make clear their positions like you do. Yep, I see it; with SegWit so close it would be disruptive to overlap it with a block size limit increase combined with a sigops limitation. I do feel it was a missed opportunity not to provide a modest block increase (even without a sigops limitation) many months ago but there's no going back now. *Hopefully* SegWit will come out on time, functioning well, and be embraced quickly without a lot of angst.
You're very welcome. I do hope that there will be a hard fork proposal after Segwit which will gain consensus. However, if Segwit is adopted quickly by both the miners and users we should see a good increase in transaction capacity that should hopefully get us through 2016. The problem caused in this conflict is that there are a lot of people who aren't willing to listen to reason and facts. Time should not be wasted on them.
why can't the other miners simply orphen these blocks?
Exactly how do you plan on "simply" detecting these blocks and why would somebody orphan them? How do you classify this as an attack; was the TX that F2Pool did to clear the spam also an attack?
