To lean on "good faith" is just another way to lose your nerve and fling yourself on the mercy of blind belief.
This is a general comment that is in no way related to this particular case, of course.
Anyway, it is important to recall that with every move that is made, it will disturb someone else. Impudence should be avoided, but the trivialities and whims of Englisch are of little concern.
But if you explicitly add "if there is any truth to it" to your post, then it suggests to the reader that the story is probably false and that's not a very useful premise to start from.
The safe side is giving them the benefit of the doubt. Possibly made up, sure, but your "if there’s any truth to it" gave a most probably made up vibe. Not only is that uncalled for, it’s pretty inaccurate.
