Seriously, though, ask yourself if it matters? Your own question contains unconventional spellings of "incredible" and "disappeared", at least two missing apostrophes that P_P would never have dropped, and an i for an I. We still understood you.
If you ever read any texts written in English from about 1500 to, say, 1800, you will notice a distinctly cavalier approach to spelling. Casual writing, e.g. correspondence between friends, was even more haphazardly spelt. Johnson wrote the first dictionary in 1755 closely followed by the Victorians who standardized (standardised) everything. The idea was that a standard approach made communication easier and recognized the etymology of words at the same time.
Two linked thoughts have been deeply ingrained in the psyche of intelligent English writers for many years: it's not hard to learn to spell; inability to spell must therefore signify stupidity.
In the 'sixties the "non-élitist" approach to education appeared. This has led to dyslexia being diagnosed in 10% of schoolchildren. The poor little scraps must not have their work marked in red pen, and their spelling is not corrected, in case their feelings are hurt. The ignorant blighters are allowed into university, unable to spell simple words or to add up without a calculator. After three years of that the Government wrings its hands because yoof unemployment rates are so high.
So, as my ramblings indicate (I hope): on the one hand it doesn't matter provided people can be understood; on the other hand it matters a great deal.
One last observation: any young Chinese people I meet speak and write better English than their average peer in the UK.
PS I took the liberty of attaching a screenshot with some red pen... all in the best of humour :=)
