I agree. Owning a .WS domain is much like living in a cardboard box under a highway overpass.
The domain will keep you dry (resolve to a website) but everyone passing by (website visitors) will wonder if you're going to bite (virus attack) if they put money in your coffee can (buy your products or services). In my view, you should seek a refund and get off the streets.
Zero. Grace delete.
Best of luck in your future domaining adventures. IMO.
