I was unable to create the pair. The platform documentation referred to in the JustSwap AMA says coin listing is permissionless, but it appears that may have changed due to Fake tokens and scams. I am not sure. The Just Foundatiin administers the platform and their daily bulletin says they are using a Daily Whitelist to provide investors a list of high daily dollar volume tokens as investments and a email helpline to report scams, but it states no change in policy towards new tokens. I have written the project team and email at a different email address and asked for help. I am awaiting their reply.
