this topic was discussed at length when it happened!
https://bitcointalk.org/index.php?topic=1769542.0and until now i don't understand why they saying it like this, calling it a fork and making things so much bigger than it is!
if we start calling every orphan block an accidental fork then we should say this news almost every day.
it was a block against consensus rules and the miners paid for their stupidity. and anyone who is still SPV mining even with the problems that has happened before deserves to pay for it by missing all the rewards they earned from mining on top of the bad block.
and it is worth mentioning that bitcoin is working flawless, the bad block was rejected in 3 seconds.
