I have been experiencing this a lot lately. High bidder on a domain and with less than 5 seconds left a minimum bid to extend the time 5 minutes. And it will continue like this on and on.
Had this happen several times in the last month. Anyone else?
it is called automatic bidding not bots
you can do it too you dictate the max your willing to pay and the system will bid for you if someone else bid
edit: just realized that the bids are coming in the last 5 seconds so probably bots ye
