could you add a profanity checker and underliner

i have a problem. sometimes when i try and up load my stuff. it will say i have profanity in it. and to be honest i have gone through line by line in my work... removing everything and rewriting it with out any swearwords or anything. it took me ages! lol but it will still say there is profanity. the spell check is awesome btw. but i would like it easier. to spot out any profanity in my work. so i can upload with more ease. could this be done? please?

thank you more your time.
