I can’t offer any scientific reason why posters continue to post on this forum long after they have left.

If if I were to place my 2 cents, perhaps a sense of grudge that they have lost money. Or Perhaps a sense of civic duty to stop others going down their path feeding this dying company only to see their hard earnt being flushed down the toilet. Same reason as victims of crimes came forward publicity to warn others despite shame.

either way your $15k can be better spent to make better return elsewhere.

Good of luck to you with your holding.
