Well in the Toronto - Paris hit, there was arguement, ..., both were moderated because if you play by the rules, it is not possible that two bills travel together and pop up at random, together, a few thousands of km further ... But as you explained, the bills are marked and you asked the person to enter them ... so in this case it is possible since you are in an exchange office ... it makes sense ... I think the moderator thought that the second hit is uninteresting, because both show the same link ...
In the second case ... you are not from Paris, but from Toronto ... one of the few bill you spent there is a hit a few days later ... you must admit, it does look suspicious ...
Guess you were lucky to have three hits in a short time (and probably marking them helps a lot ...) I can understand these actions ... but I also understand the users get angry when falsely moderated ...
I think the discussion will go on for some time

Time is on our side ...
