There is nothing illegal about repeatedly buying clothes, then returning. If I do that enough the store may bar me from the premises for being exceedingly annoying, but they certainly can't charge me with anything.

Another example is a cafe.

Get a bunch of people to repeatedly queue up but when they get to the counter decide they don't want to order anything.

Just the sight of a long queue outside the door is going to put off legit customers

Clearly Uber are engaging in activities to disrupt and cause harm to the business of their competitor.

I said it was fraudulent, which it definitely is. Whether or not it fits the legal definition of fraud is debatable.

Some localities do have laws forbidding buying something with the intent to return it.
