Ive never had any trouble on there, except for one Nigerian scammer who won two old phones Id put on, then sent me the same email for both phones saying they were for his mom in Nigeria and he would pay me £100 postage for each phone, which were only worth about a tenner each!
He said hed send me the money once Id given him a tracking number - daft *******. I sussed it straight away and told him to **** off, then the cheeky **** sent me another email threatening me with legal action if I didnt send them. It was funny as ****.
These are the real scams to watch out for on ebay, but they're so blatant that if you fall for them you shouldnt be using the internet anyway. I still use it to buy stuff, just cant be arsed to sell stuff lately.
