Happens alot seemingly random linking up of eBay accounts, in this case we have a person who had a eBay account at one point, had buyers basically screw him with a serious of damaging chargebacks and get suspended, fast forward 2 years, his mom now signs up to eBay with her own details, her own PayPal etc. and eBay decide to link these accounts although it seems theirs nothing linking them (how/what/why we will never know). In that time there IP address and other details must have changed so how did eBay know? This raises the question :
Does this mean that if a company had 100 employees and one of them scammed on the companys IP, that every employee would have their account revoked?
