Example i have been through when i lived at my mothers a few years back.
Mum had an account, Sister had an account, i had 2 accounts maybe 3.
I becamse a victim of fraud through ebay where i was scammed out of £800, paypal was in red, neg feedbacks flooded in as i was young, no sense, was dropshipping, i couldnt do anything but refund them and be in the red with paypal.
I dont think back then paypal was linked to ebay, but because of the bad feedbacks etc high risk stuff i was selling also i was suspended, few days/weeks later, mum and sister were banned.
They did however after about 5 years of moaning to me that they couldnt sell on ebay etc etc as my mum was addicted, you know what their like selling everything they could find. They are back on, same isp, same address, same tel, same names the lot, ive moved out they have been trading now for a few years no probs
