That is why no one can see the numbers at the refreshing time and it always says the limit is exceeded, and also I would like to know if anyone successfully submitted it in the last two days.
I somehow got lucky to time free slots open for acceleration the other day (3 days ago). I am able to insert my pending transaction to get accelerated. It was 48 free slots when I sent my request to accelerate, it does not take that long to have this free slots consumed.
It looks like someone had built a bot to be able to claim the free slots of Viabtc since after that lucky instance, I am unable to timed the free slot of Viabtc to accelerate transactions.
