There is absolutely nothing wrong with suspicions. St. Francis is against "rash judgments" but says nothing about suspicions, which are not judgments at all. Christ Himself suspected the Pharisees of trying to draw Him into verbal traps -- would you say He was being "rash" and unfairly judging the Pharisees, who may have just been trying to get to know Him better? Was Jesus being "rash" when He didn't blindly trust the devil who offered Him the world, was He wrongly suspecting the devil who might have had good motives at heart?
I'm sure 008 that you have heard we should be wise as serpents and soft as doves. Does one become "wise as a serpent" by trusting everyone until it has been proven in a court of law that they are malicious?
I get really tired of people hiding behind accusations of slander when any kind of evil or weirdness is pointed out. It makes me automatically distrust them. We live in an evil, weird time, or haven't you noticed?
Then you say we must have facts before speaking, once again contradicting your own article. St. Francis de Sales says: "If there be only a slight appearance of evil, say no more than that; if it be a question of some trifling imprudence, do not make it out to be more." A "slight appearance of evil" is just that, an appearance that leads to suspicion, not a provable fact that evil is being committed.
I could have stated actual FACTS that may have been seen as damaging about my experience with the sedevacantist clergy, but preferred simply to put people on their guard. Some facts can be deceptive, or lead to conclusions that are wrong, or seem more damaging than they really are. Facts can be much more unfair than suspicions; they can be taken out of context to make wrong judgments.
It is the motive that counts. As St. Francis de Sales says, we must measure every word carefully, while truly wishing for the good of our brother, not speaking maliciously or with pleasure in another's problems. That is the key. What is the motive behind the revelation: Is it the exposure of evil and/or heresy? Is it to protect children? Is it to protect ourselves? Is it to push someone down to build ourselves up?
