I don't think these two accounts deserve a whole theme.
OP, for the future, consider posting such posts without creating separate threads for each alternate account you find. There is a separate topic for this.
https://bitcointalk.org/index.php?topic=2544574.2900But as for these two accounts, I can assume that the owner of the
Toukir_babu account lost access to his account, and as soon as he realized this, he began to post messages from his other
Rafi_Rahman account.
I don't see any cheating violations between these profiles.
At least there is nothing yet.
