@Tom maybe unlikely but that doesn't mean these things don't happen. Arthur Andersen was founded 1913 and it died in just a few months.

"As for what a scammer could do if they have a copy of your utility bill, there's nothing in the bill itself that is sacred so the information itself isn't really a risk." - note that this is country dependant. You are probably correct about US, don't have an idea how it is there and this is tagged as such. But for example in UK, an utility bill goes a long way to prove you live somewhere (and is pretty much the standard way to prove such a thing), so would not sent it to fishy parties.

@Harper-ReinstateMonica the comment I replied to used this formulation: "it's NEVER fine for anyone to demand your login credentials to anything.". I would think, especially for non-technical user, even with oauth the site is "demanding your login credentials to anything" - it is demanding them to do authentication somewhere, even if using another site. It is not demanding them to site itself, but it is asking you to supply them to "somewhere" to be able to use the site. This was my point.

@jwenting do note that even site we're discussing on there are google, facebook login options even though this is neither facebook or google... is that equally suspicious?

To me, the point was not about prepaid card thing, but "I should never give them my bank account information" comment by OP - you shouldn't. What you should ask is to ask their bank account information and then just do a IBAN transfer. If OP is asked to provide information about their account, it sounds like a scam, as that shouldn't be needed if debit collector is legit.

@RonJohn I disagree. debt may be legit, but doesn't sound like debt collector is.

while I agree with this answer, it is a bit counter-intuitive that your main point in this answer is to buy some time and delay any major decision, and you end with a video of which the main point is "start saving now, don't wait a bit"

@KateGregory I agree - I was just provoked by the comment by Ismael Miguel about this being a life lesson. It may be suitable and even ok in some situations, but I'd definitely not recommend it to be a guideline to live by.

I would totally freak out if my parents would ask me about this, even though there is nothing there. It is absolutely not my parents business, just like it is not my business to inquire their credit reports.
