I actually had this happen to me, but the bidder with 20+ bids didn't win and the card sold around market price - but when I saw all the bids long before auction end, I kind of shook my head and said people will think this is suspicious. It may not actually be a bad strategy for the buyer if it scares away bidders. But that actually doesn't help with a reservation price on the auction since its not possible to bid yourself up, the auction could just end as "reserve not met." It's also a good argument for sniping given how small the bid increments are on eBay - say someone puts a bid in and forgets about it - someone could come along and slightly outbid them by just "nibbling" them up time after time until they get ahead.
