Polite manner? If you behave abusively do not expect those targeted or subject to your abuse to react passively. You are clearly behaving as a bad actor. New players should not be expected to "stake" anything (despite the fact I have). If Splinterlands is an investment vehicle rather than a game it should say so from the outset and drop the "game" pretence rather than lure people with promise of a functioning game. This would of course mean that the developers would have to register as an investment vehicle with the various financial authorities around the world on risk of direct legal action.

I would suggest that if you want to invest in stuff you focus on things that designed to be upfront about their investment status rather than hijacking a game. You bring the community to shame.

Again you missed the point that it is close to impossible for new players to sell as they have nothing sellable.
