Trust can be a very expensive thing
Unfortuantely, you learn't this the hard way. Although not on the same scale, I can see comparisons between this and socially engineered scams.
Before you say that the actions done within this thread aren't against the rules, neither are socially engineered scams as in FPC's eyes, you willingly gave your item to another person.
I guess the long and short or it, the actions were immoral, dishonest and will end up costing the perpatrator alot more that the few ped he will have got in loot
