Or 3. Rancho got rich off of haejin's advice and wanted to repay him.

It could all be innocent. So why not address it? Say that. Realize though, that his actions could be a detriment to the platform overall. I wonder how long he would have continued to reward haejin had the community not said anything? He (I use 'he' for simplicity, could be any other entity) seems to be able to read and speak English. Why not just address it publicly?
