Thank you for your advice and your help. I could have done that, thats true.
So, how i see it is ok to use those placeholder images. To go on and keep everything running i would need to change the photos in the announcement thread right?
I can tell you that in the crypto world the trust is very important. You have to be very professional in what you are doing to actually not ruin your reputation. Once you make a mistake, it takes a lot of time and effort to rebuild back the community trust. It's a long and hard process.
If you put all your cards on the table and keep your business transparent, that will be positive thing. If you think you will be capable to maintain your project, you go for it.
As for the feedback, it will stay there until you regain our trust.
