Creating pinterest bot accounts

  1. What is best for creating 20-30 accs: using android emulator with multi devises or simple browser with proxies on home PC?
  2. What is best to name bot accs like: Jenni, Sara or niche names like Fitness Motivation, Fitness Life
  3. I dont see likes, repins in browser or Pinterest app on android, so I cant repin popular other pins. I know it is good to repin popular pins.
  4. Is it good to do following 100-300 from every acc?
  5. How many boards must have every account?

Anyone? Some tips?
