I doubt that occasional sale of a possession that’s no longer needed - like me selling my old Hostess Trolley - is going to raise queries. For those who are doing it as a business, or a regular income-generating sideline, it’s a different matter.
Agreed.
My niece sells a lot of old clothes on eBay and Vinted, as she is young, fashionable and skint. She operates a 'one in, one out' policy, and when she buys a new item she sells the old one. She's not making a profit, but has quite a turnover. That's very different from someone importing tat from China and selling it on.
Another consideration is that some eBay sellers have thousands of sales, but don't register as a shop, which means that buyers don't have the same protections (eg the right to return items), which is unfair both to the buyers and to more honest brokers who do declare their business status.
