Lots of scammers on gumtree ATM. One of my workers almost got scammed over the weekend on gumtree. She wanted to sell her mobile phone, so someone offered her the amount she wanted plus postage overseas. The person said he had already transferred the money to PayPal, insisting that she post the good. On Saturday she received a bogus email from PayPal saying that she is breaching the rules and she is going to get charged. 

Being the first item she has ever tried to sell, she was afraid and she couldn't send the item because it was the weekend. A call to PayPal discovered it was a scam. Lucky for her it was the weekend, if not she would have lost her phone.

so many dodgy crap to worry about now adays.
