Not always; they could just be quote stuffing

  It doesn't work like that. You can't cancel a bid/ask after someone in the market takes you up on it.

    You can move your ask up as bids get closer

      Sure, but market orders or bids that cross your ask will trigger a transaction at your ask price. I’m sure quote stuffing happens, especially deeper in the order book. Or with very small amounts closer to the cross.

      The context here was the highest bid / lowest ask. The context was not orders deep in the order book. If your order is the best order available in the book, anyone can just take it, and you will not have any time to move your order before a trade is executed.
