At 04:20 UTC on 20 April 2021, we reduced the threshold used to detect spam orders from 0.01 XBT to 0.0001 XBT.
After this change, accounts with too many open orders with a value less than this threshold will be considered a Spam Account. For more information on how such accounts are affected, please see our Order Minimum Size Limits.
We will also be turning off the Quote Fill Ratio rule, starting at 12:00 UTC on 22 April 2021.
