Hey,
Here is what triggers a Grammar & Profanity rejection:

Could be too much caps, punctuation or symbols
Sometimes the landing page and even the content gets flagged and any subsequent submission will reject. Sometimes if you submit a lot in a row that get rejected, the account gets disabled.
Other than submitting and appealing 1 by 1, I've not found a solution to fix the root cause.
