People have been searching for fake team members for a while now.  Maybe you are just upset with yourself for not knowing that picture/photo recognition was possible on the internet.
Now, you must blame someone else, such as  "junior hackers" for hacking some scammer computer to upload pictures, just to make you feel better.

If the hacking case is true, investors should be even more skeptical about investing in this project, if your controls are so weak that allow a "junior hacker" to gain control/access to the website.

And as you said,  it is a discussion forum, and we don't need to discuss with you,  you are not a member of the team, right?
