Proxy Reserve ?

I have been an e-bay user for many years and have 100% feedback Lately I have been buying quite  a few items from one seller  I have noticed recently   ( could have been going on for some time ) the same person is putting a bid in that increases markeldy the cost of a  winning bid.

 

I can understand the seller not wanting to loose money but if this is the case they should put in a reserve I have been monitoring the site and every article I win this same person pushes the cost up markeldy I know this is not in the spirit of e-bay and this is not fair

 

If it is an aquantance of the seller creating a false reserve can this be monitored /investigated

I look forward to a repply
