It's so easy:
- telegram are ideal place for manipulation:
   - they can ban anyone
   - they can flood whole channel with different 'members' (in fact just their own staff)
so, end result are artifical made and have no relations with real life

- their target auditory prefer telegram
   just millions of young idiots who's drown mother's money for ICO's

- work with this auditory are cheap.
   One~two students working as 'moderator'or 'support'


So, here we go: cheap manipulation of idiot's herd.
