I'm here and answer all questions, what would you finally understand. That you are wrong.
Have you got the permission from real person to use it on your site then? If yes then I would like to see them (Better if you post them here). If not then you could have used sketch or some cartoon-type edited pictures well but you rather chose to put pic of some random people who might have problem of you using the photos of them in your site.
We will speak frankly. All the people on the site were generated randomly.
Because no one in our team wants to show themselves.
Are you interested in the team?
No one wants to show themselves means you can use anyone's personal profile pic without permission and risk their safety without permission?
Secondly, what about your site which looks like you might have copied it from idap.io
http://archive.is/Y2puV and
https://www.idap.io (
http://archive.is/asHoY). So who copied it? was it you or Idap.io copied your site's template.
