All that we have said about [rechiluth being] forbidden applies even when it [the story] is absolutely true, containing no admixture of falsehood. And not only when they have loved each other from the beginning and he [the speaker] goes and bears a tale from one against the other, is he called "wicked" and "an abomination before the L–rd," viz. (Mishlei 6:16, 19): "These six are hated by the L–rd, and the seventh is the abomination of His soul… and the inciter of strife among brothers," concerning which Chazal have said (Vayikra Rabbah, Metzora 16:61): "This seventh ['the inciter of strife'] is the severest of all." But even if in the absence of this [rechiluth], they bore great hatred towards each other, and this one [the speaker] went and bore the tale, he is called "a talebearer."
