A bit shocking from a company that prises itself with security.
I had a business account, I was selling electronics. Few a scammer (I figured later that it's the same person each time) tried to scam us. Each time we sent a refund to the credit card scamer used (seems to be stolen)
Each time we sent an email to Stripe with all details of transaction and correspondence we had with the scamer to help them with figuring out how those scamers operate. We thought we're doing a good thing and Stripe seemed to appreciate the effort.
Suddenly our account got blocked for selling not original electronics. A bit ridiculous reason since we buy all electronics from either authorised agents or manufacturers themselves.
We were contacted and asked by Stripe to provide a letter from manufacturers that confirms that the products we sell are original. I said that I'll try to get it, though I've never heard of such letters before.
Their customer service rep promptly replied that we should start looking for new payments processor instead (!). They couldn't be more clear that we are no longer welcomed as customers.
They're not a bad company overall but my recommendation is do not try to help their frauds department! Do not send any emails or addresses recieved by scamer, just let the scamer keep scaming their customers, otherwise you might end up with your account blocked.
Prior to the above we had no problems with Stripe. All seemed to work well, payments paid out on time etc
