babadook your first paragraph was so compelling that I can hardly type this sentence because I want to say harsh words in response to it.

That said, I think tradesonred is right in this case. Without some PnP rules, its way too easy to grief.

If griefing is allowed then every raid encounter needs 6 to 12 extra players or more just to go around keeping trains from being made.

It falls into the category of exploits, which are in game mechanics that are considered illegal to deploy because of their broken nature.

The game isn't coded well enough to stop all exploits from happening, so they are just not allowed, and you get banned from using them.
