i personally think the trust system does work , its been in place with other breedables , in my instance with the horses i have given and recieved studdings, both time the person passed their horse over for the studding and was returned afterwards , ive met many people and made a lot of friends through this in 2 yrs ive never had a problem , sure they may be the odd bad apple that doesnt reurn the mossm to the other person but once their name has been spread about they quickly leave the game , people dont trust them , refuse to buy of them and generally are weeded out completely , so in the last 2 years i have enjoyed this system and as have said made a lot of new friends through it
