This will be a problem I'm afraid!
Any link to another account, then both incur the same restrictions if one has a batch of defects to bring them below selling standard.
Any idea who this account belonged to? A family member? A friend ? If it's a totally random account, then I'm afraid if they have a permanent restriction yours will have to.
Calling eBay CS , use the Help & Contact tab above, is a problem now, as their lines are down, Live Chat is available from time to time, you can try asking, but they usually do not reveal any details of restricted connected accounts, but they may tell you if it is a timed restriction or a permanent lifetime one.
