I had made a useful reply to not only that OP but 2 others over about a 2 hour time period that were all ghosted - so I wrote that crap reply and it wasn't ghosted.
My point was, there seems to be no rhyme nor reason to what handles or posts by those handles are ghosted and what ones aren't.
There are a couple of handles in 3 that never have anything but kindness in their replies as well as being informative and some of THEIR replies are ghosted.
Then I see someone(s) being snarky, rude, calling someone(s) names, being insulting or trolling and those comments post to the forum.
As I keep saying ... there is no rhyme nor reason for what or who is ghosted when, it "appears" to be an entirely random "FU" that just makes the rounds hitting here and there in public forums, and sometimes landing on one or two handles for the better part of a day.
Frankly, it's not worth the effort to offer good help when you then have to go check another device to determine if your reply was found worthy enough to be allowed to post, or if it's going to be randomly ghosted for no reason that can be determined.
This is either a sick sport for some staffers or their programmers suck.
