oh gosh, big hugs, wow you have been through it.
Unfortunately this is the reality. People have this false sense of Disney Bubble, where everyone is just the nicest of people and everyone has the same morals as you. The reality is very different.
The reality is a lot of people have a me me me, sense of entitlement and will find loop holes and ways to bend the rules, basically the Disney version of white collar crimes, sure why does it matter, its only Disney, no one is being killed mentality.
Yes. They use software to get the dining reservations and then sell them on.
Its also how the Disney resellers make their money. When there is a high demand merch release, they are the ones waiting in lines and buying multiples. The personal shoppers you see advertised on social media, yep thats them, using their Annual Pass to go to the park, buy the merch and then sell it online for profit, at a far higher cost than the original in park price.
Theres so many side hustles which are big business, all finding loop holes to make money from the first time out of town, out of state and international Disney fans.
