Already received 2018 ESH as a free gift I would say thanks for the tokens, but I've seen a lot of ethercash official channels on twitter, it really confused me

The rules were for accounts above Full Member, how did you receive it? Do you have another account? What does dev have to say about this? So far, I haven't received a single ESH! So in this way, the rules have changed?
I think you received ESH tokens

The distribution is not over...
