Key features about the account:

- There are around 18 friends connected to the account
- The username consists of 6 characters
- Different profile pictures on Faceit and Steam
- Steam profile picture is an abstract form, slightly resembling a flower, in purple and white.
He also has 2 routers in his house . One for security , so basically you do not see his original PC ip adress but the security one .
This is his steam id : STEAM_0:0:217198832
This is his main profile : https://steamcommunity.com/id/sebasto23/ (this profile doesn't have any other accounts of his in the friends list)
