If it's someone else's profanity, maybe leave the first letter visible so that people can tell what word it is without the word itself being visible; if it's ...
In order to not draw attention to certain words you could blur these words and a random amount of other words as well.

Thus there is some blurring, but as it's 'quite some blurring' no particular attention will be drawn to a few particular words
I never include the http/https -- few consumers are cognizant of the s being there. Many merely look for the lock icon in the browser if they are concerned about security.
It's only those in the tech industry that may even be aware of what the s means.
In short, it's not a selling point for a large portion of the public.
....and either way.....
