Don't use the new account as puppets to introduce your platform here. It does not have any effect on the trust of the community for your platform. I see a bunch of new platforms being created and all using new account. It is a completely useless and stupid strategy
Not only it does not work, but it also makes me feel that your platform is not worth trying, because a reliable platform will not promote this way. There is no reason for someone to try an insecure new platform, just stay with the bigger proven platforms
