People shouldn't expect that you can run a business as though it were a lemonade stand and funnel hundreds of thousands of dollars through any processor, including paypal, without anyone taking notice. That's not the way banks work, it's not the way the law works.
Get a business license, get your ducks in a row, make sure you read the terms of use, make sure you understand the legal implications of the business you are conducting, and then proceed accordingly. If you run into problems with a bank, a processor, or whomever then go consult someone who knows the law far better and can act on your behalf (e.g. a lawyer).
This is the exact same advice whether you use stripe or paypal or authorize.net or what-have-you.
If your business operations are indistinguishable from fraud or money laundering on the surface then you should not be surprised if your accounts get frozen and you should ask yourself how you need to go about making sure there is a perceivable difference.
Perhaps one could argue that the law or banking regulations or the corporate policies of the most popular services were different, but that's the world we live in. And it's not because they are trying to be assholes, it's because fraud and money laundering are commonplace, and if these companies don't try to keep it in check then they will get shut down by the government or the fees you pay to use the service will be much higher.
