It is also very common.
They can be proved to be incorrect, for exmpale if they refer into their own ToS, which is public information and binding. And then some legal expert says that this is not how it goes and it ends up into court, because customer sees risks being lower.
If they made a mistake or there was a software failure, it is bad PR.
If they ban someone for some specific reason but not someone else, there will be drama.
It is very beneficial to just say nothing.
In most cases, you will not be given details if fraud is suspected. The reason being that companies don't want to tell fraudsters how they got caught.
The real culprits here are the people trying to violate the TOS, plus everybody's desire for cheap services and easy onboarding. The historical alternative was very expensive setup (e.g., spend a few years building a relationship with your local bank branch manager and establishing a financial track record). Making it easy to get started means that most problems will show up down the road, and the lower merchant costs means less money to pay for smart people to carefully untangle the truly dodgy from accounts that just look that way.
I get that, but I don't see how actually telling people what term of service was violated gives too much leverage to the bad guys.
I have seen way to many stories about people claiming to have been banned for no reasons from services (online video games are a popular one) before it is revealed the ban was 100% legitimate, to take any new story like this at face value.
I made a mistake out of inexperience, was refused the chance to correct that mistake, and all of my PayPal accounts -- including my PERSONAL account that I had had for years -- were banned because they were started by a person (me) who had an account frozen or banned. Is that a legitimate enough story?
PayPal had banned me because I was under 18 when I opened my account, they then allowed me to open a new one (right after this one got suspended) and it has been working fine without any issue since then (10 years+).
Stop doing shady stuff.
If PayPal requires an SSN or EIN, why do they even allow you to create an account without one?
The guy can't keep his story straight for 3 lines on HackerNews, he is obviously doing stuff that he shouldn't and using his PayPal in a sketchy manner.
One year ago this month, Twitter permanently suspended a 340,000-follower account for “repeated violations of our COVID-19 misinformation rules.” The owner of that account, the former New York Times reporter and vaccine skeptic Alex Berenson, responded with a lawsuit demanding reinstatement. . . .
. . . Earlier this summer, Twitter put Berenson’s account back online, noting that “the parties have come to a mutually acceptable resolution.” Berenson wasted little time in calling out mainstream media for failing to cover the “pathbreaking settlement” that led to his return. . . .
