Making splinterlands post here on Hive is like preaching for your own church, it's why I try to be as active as I can on X and post my content there and on Publish0x as well.
Keep doing what you are doing, I think advertisement is a good thing, hopefully soon when everything is set to go and Blaze gets the all-go signal, things will get phenomenal
