When I was in corporate IT, I got way too much internal email that looked like it had been pecked out by an autistic second-grader, with random spelling, capitalization, and punctuation. Which wasn't as much of a problem as the chain-of-consciousness blather of jumbled words that often made no sense at all.
Some of those people were Ph.Ds in charge of multimillion-dollar subsidiaries and dozens or hundreds of employees, but they may have well have been trying to communicate by interpretive farting and tap-dancing.
