Is it able to everyone?
User 1 -> Uses VPN x to access bitcointalk from a particular IP provided by the service.
User 1 -> Creates bots(newbie accounts) to post spam messages from the same VPN/IP.
User 1 -> Gets banned by a forum admin multiple times,IP gets flagged as "spamming bots"
User 2 -> Uses the same VPN service to access bitcointalk.VPN provides them with the same IP used by User 1 (flagged currently)
User 2 -> Flagged IP gets detected for previous evil records.To ensure safety,bitcointalk asks to pay some bitcoins as a fine for the mischief done in the past by User 1.Less do they care who is using the service.As long as IP has been flagged,you gotta pay small fine.
