So I was setting up some bids on Bidding Scheduler and got this message:

Maximum amount of bids setup for around this eBay ending time has been reached.
eBay has setup new security measures that affect bidding on multiple items that end around the same time. As a result, you can only submit up to 4 bids within an 30 minute timeframe. Sorry for the inconvenience this may cause.
Also note:You can still setup bids for items that end outside this timeframe.

Does anybody know what this is about? This effects me as both a buyer and seller and can't imagine they would restrict bidding on more than 4 items in a 30 minute period.

Thanks
