Number Of Custom JSON Operation On HIVE In 2022 | A sharp drop in June! Why?

Who is behind most of the custom json operations on Hive? Splinterlands of course!

What happen to Splinterlands at the beginning of June 2022? A new reward system was introduced. Ergo a lot of bots stopped playing/farming, and the number of accounts making custom json operations on chain dropped from 350k to 150k. A 57% drop.
