Hi, I would like to know from anyone at what point would you block certain buyers and what for? I have had a customer who thinks it's fine to bid on several of my items over a 3 week period without paying for any of them. I had contacted them to let them know that they need to pay for the items that had ended, they didn't seem fussed and said that they would pay for all of them when the last one had ended. This happened twice, so I blocked them.

Also had one customer who bid on an item and when it had ended I received a message asking if I could cancel it for them because she liked another one better. I explained that you need to be more careful in the future because you bid on something you buy it...I cancelled it for her. She bid on another item and she never paid for it...so I blocked her too. 

Is this fair or too harsh?
