Do you have any older address posted except that from stake btc address thread?
No, because I have bought it from the original owner outside of this forum and he has not never posted any his bitcoin address in this forum.
i dont think its worth 0.15 coins for a full member just my opinion, also was it banned previously?
No, the account has not never received a ban. At the moment he is enrolled in a signature campaign, and always paid (for almost all) his posts.
