, the exploit exists, very very old and well known BUT it's an OpenTTD bug - without changing server code, nothing we can do
His usage is forbidden and covered by our rule #4 "... Also cheating to advance yourself ahead of the competition unfairly will not be tolerated." because it gives an unfair boost on the CV.
I usually ends on points removal (sometimes ALL, other times from last 10 games) and when repeating, account lock and ban from games.
When we suspect someone uses the exploit or when a suspiction is pointed by another player, we investigate. We check the average use of trains (or any other vehicles) among the games and compare with the suspected games. Since average number of trains on server #9 is ~100, you had on game 2148
414 trains and
493 trains on game 2149 so, was easy to spot.
We recommend NEVER use it, for the told reasons ^^
About a solution, it's on ttd devs
