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.
The benefits of transparency and accountability outweigh perceived costs.
I know members who have been suspended and none of them seem to have any problems coming back after that suspension. I doubt that a public notice of that suspension would do little more than encourage people to understand why that member went on a little trip on the RV and would also make it clear why the suspension occurred, perhaps keeping others from taking a similar trip in the RV.
