If you show what you deleted, it's not really deleted, is it? It's right there causing almost as much disruption as if the board were not moderated at all. If you show that a post was deleted without showing the content, that just raises distracting questions unrelated to the mission of FT and doesn't satisfy anyone.
Similarly if you publish rationale for suspensions that could impair the member's ability to rejoin FT successfully, with everyone letting bygones be bygones. I don't see any benefit that outweighs the damage to FT this proposal would cause.
C'mon,
nsx, you wouldn't keep the post content itself, just an empty post saying "This post deleted for TOS violations."
