Restrictions and payouts on hold differ from account to account, no one here can tell you the length of hold on your payouts, though I understand some have had holds of 180 days. A permanent or an indefinite restriction is lifetime ban from selling on eBay, it's not given out lightly.
Not sure if contacting Customer Services will help as they do not explain any restriction in detail, if you wish to ask , this is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open 8 a.m. - 10 p.m. on weekdays

Automated agents will be available on chat outside of the above hours.
I recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
