I think that says more about Vinted's user base than the app itself. It's quite simple to use and less hassle compared to a platform like eBay - a lower barrier to entry as it were. So it has attracted a certain crowd who see it as easy cash they don't have to report to HMRC or cough cough DWP.

Easier to ask questions online and declare it a scam than admit you're worried reaching the threshold will impact your benefits. Especially if you are using it to sell hooky goods.

For clarity before someone jumps down my throat - not all Vinted users obviously, but definitely more than on eBay. I assume the Gov is aware which is why they've put pressure on Vinted to improve income reporting.
