Exactly, people in Venezuela spend HIVE and HBD too fast and so teh pool is being drained daily. When we had Haijin cleaning the SteemPool back in the day of Steem, everyone were very angry cause this was a huge flaw in the earning system. Heijin upvoted all his posts with huge amount of steem and he collected like 20K a month. But ok that's a diferent story.
So, Hive changed their motto and not tellig people that you can Earn on Hive but in Venezuela this is the only reason people are on Hive and they onboard people to Hive who will be earning and taking all away.
The reward.app has turned everything upsidedown and now since all the earnings can become liquid makes it more apealing to just withdraw everything. At least with the original system it was 50%/50% and I think that reward.app should be disabled.
Unfortunatelly, automatization things can't be disabled as there will always be ways to do it... look at Splinterlands and bots... You kill 3 "public" bots, while "secret" bots are still working...
Education of users could help, but on that side, people are too lazy to listen... lol...
