Ebay Help needed.

Ziggymon

Hello im a bit concerned about an item I have on auction on ebay (150363368237). Its been going really well with lots of interest but over the last 2 days I have had 2 bid retractions and I do believe they were in breach of the ebay's rules looking like these bidders were trying to find the max bid of the current leading bidder. I am worried that because there are two retractions other potential bidders will be put off.

What I would like to ask is there anything else I can do other than reporting these false bidders to ebay? Any is there anything I can do in the future to try and keep these people away?

Thank you very much in advance.
