SPV mining *is not proper mining*.

Is that not clear to you?

It is irrelevant whether or not they use the SPV protocol to do that so (and in fact they don't as they use the "relay network" which existed a long time before SPV support was added to Bitcoin) so your desperate attempts at trying to discredit me are failing and just making you look even more stupid.

If you mine that way then you end up on a fork (as has already happened) and as I have already tried to explain (but seemingly you are incapable of understanding) the larger you make the blocks then the easier it would be to trick other miners into mining on such forks.

And btw - the only *flawed understanding* here is your own.
