In most cases the lies won't affect your reinstatement, cuz the elders involved will only be concerned about whether or not you have repented and no longer lead a lifestyle that
caused you to be df'd,, however on the flip side,, because of all the lies, rumors, etc, the r/f and will always view you according to those lies not according to what really happened.
Though we are told to forgive and forget, in actual practice those that heard the lies and rumors will always consider you 'marked' in some form or another.
But what else should we expect? The JW lifestyle is so unfullfiling, boring, repressive, therfore the general jw public grasps onto these rumors with full might so as to attain some
excitement in their lives. There's nothing more exciting to the brothers and sisters than to 'talk' about so and so and what that person did.
