I think I'd argue that the profanity is for effect/emphasis, and to mark the post out as a rant - it's clearly (to me) being used intentionally as a writing technique.
Which suggests 'gratuitous' is a harsher adjective than strictly requires, and may simply reflect that you aren't fond of profanity's use at all.
I think either dropping the word entirely from your comment or perhaps replacing it with 'prolific', which would not only have been non-judegemental while still conveying the key point, but additionally alliterates nicely too.
"Gratuitous" is a judgment: profanity loses its shock value if you lace everything you say/write with it. I don't know if the rest of her writing is like that (my recollection is that it isn't), but this piece was too heavy on it. A well placed "fuck" can add a lot, if used judiciously, but it's the kind of thing where you only sit up and take notice of it due to its absence elsewhere.
