Are There Bots Bidding?
The short answer? No. The Long answer:
We use a feature called Max Bid in our auctions, which lets you 'set it and forget it' instead of constantly having to watch your auctions!
For a tutorial on how that works, see our What is a Max Bid? article.
Because of how Max Bidding works, sometimes it looks like there are bots bidding on auctions if you aren't aware of the feature. But its actually other bidders like you making using the Max Bid feature!
