I mean, I've heard stories of someone reported to HR for using the word 'baller' (as in 'That new car is so baller, David.') who clearly did not understand the meaning of the word and I can only speculate as to why they thought it was a vulgarity.
That said we can always strive to communicate more clearly, and someone publicly blogging about how they quit because of it probably doesn't get the same benefit of the doubt.
