Absolutely free things/selling things brings out the worst people.
In the US here, we also just put it on the grassy part on the other side of the sidewalk, someone takes it. Good.
Smaller things we save to send to family in my mother’s home country, whatever isn’t appropriate for there (like winter clothes are too hot for there) gets given away to friends or donated to a local charity shop.
eBay long ago was good about protecting sellers and enforcing rules. Now trying to sell anything is a joke. Lots of people either just playing with the bids, lowballing, trying to scam, or deciding they bid too much and try to put the blame on the seller.
I only sold items here and there to make money when decluttering. So items were one offs. I made sure to take multiple pictures and specified what kind of light they were taken in.
I had a couple of people get shitty because they asked about color, saying it looked such and such (way different to what was the actual color) I explained the color was as described in the description and how it appears varies due to their monitor/device. I was not rude, just stated it in a matter of fact way. I had one get defensive and another snarled at me that I was lying and she/he wasn’t stupid and that all meant my item was a FAKE! 
When I worked cosmetics, the free gift with purchase and samples brought out the worst people. People that would insist on samples to sustain their daily use, want multiples to sell, never ever an intention to buy. Samples are for people to try, one won’t like every sample, I don’t always buy when I’ve tried something. Yet I try the sample because yes, I have intentions to buy if I like it.
Same for the makeovers. People would act like they wanted just the eyes done, then say, how about a cheek color, and so on until they had a whole look.
Wasn’t allowed to say no, yet got told off when the people wouldn’t buy a thing (they never intended to)! Some got the full face asked from the start, but didn’t buy. Like one that needed makeup for pictures. Some bought the things they’d need to touch up for their event, then return the used items.
Same with food samples. I worked that once, and it was amazing how people acted put out when you didn’t give them the pizza slice size they wanted, demanded more yogurt (then gobbling it down then saying I don’t need to buy it, I already knew what it tastes like).
