I see ne ĝenu vin fari tion used sometimes to mean don't bother doing that but sometimes don't hold back, feel free to do that which is entirely the opposite sentiment!
For example, if someone says ne ĝenu vin pro mi I wouldn't be sure if they intended to mean don't trouble yourself because of me (don't do it) or don't hold back because of me (do it!)
Is one of these an incorrect usage or is it simply something that needs to be worked out from context? Is there any way of phrasing these kinds of statements to be less ambiguous?
