It depends on language. Like for Chinese it's a characters have meaning and spacing and punctuation makes no difference so everything is squished together sometimes. It bothers me cz it's brain overload of a second language but for ppl with it as their first language it's probably easily understandable and still correct.

I'd also go crazy with all those spacing errors. I read along punctuations, which means that no punctuations = rush and breathless. It's like, why are you rushing me? Why are you rambling?
I'm not gonna print out spacing manuals though, lol
