He loses his reputation for not keeping his promises
Actually he does not Lose reputation because of Not keeping promises but for Ignoring His obligations instead.
He is acting in his promise when he says paying when he made a post , but that will happen months after the supposedly pay time.
Isn't that sort of the same? I mean his promises are his obligations as well. What is your obligation as a casino owner? You promised to pay your signature wearers their amount and then you need to pay that, that's your obligation to pay but it is also your promise as well. If people put money in your casino, they should be able to withdraw it with hot wallet filled enough, that is your obligation but casinos promise that you can withdraw whenever you want.
Moreover, I would say that it is very important to have this kind of thing, it is both obligation AND promise at the same time. I can't say if you could do something without getting people give up hope about this place. Lightlord managed to build a big big big reputation over course of many years, and then managed to destroy it within 6 months, that is the quickest someone destroyed such a huge reputation if you ask me (at least in crypto).
