My email is: bojanboyss@gmail.com
Artists managed by me (Bojan Boyss): Second Escape and Boyss
(you can find more info about each by clicking on their name).

Because of the privacy I can't list my email everywhere on the web in public, I use this email for all the things on the web, hope you can respect that, but here it is and hope that's enough proof that I'm behind those artist profiles on Spotify.
Furthermore I can provide screenshots (bellow) I just made where you can see that I'm logged in as Second Escape:

I have a twitter account but I use same account for all music projects and for sample library development.  Link: https://twitter.com/BojanBoyss
Same for Facebook too: https://www.facebook.com/Boyss2School
Never used Instagram.

Hope all this will be helpful
