Getting harrassed

I had a buyer contact me about postage options for an item. Even though it was a pick up only item I said I could post it for her (as she said she had just had surgery) OR that depending on where she lived I also offered to drop item off at her house. However she never ended up bidding! I think she assumed we were doing a behind the scenes deal but she never openly offered to buy it outright so I wasn't aware. The item sold with one bid to another buyer when the auction ended. The lady is now messaging me calling me all sorts of names e.t.c! I didn't know she was wanting to buy it behind the scenes (which I wouldn't have done anyway) I thought she was just enquiring about postage option! Have reported it and tried to block them. Question: Does blocking them from bidding on my items also block them from sending me more messages/emails?
