Same telegram in both posts

Same telegram indicates that the owner of both the accounts is a single person.
Also the second account "Airtman" made a post regarding thread bumping which means that he is a thread bumper. (Which is strictly prohibited on the forum) Also he has earned some negative trust for doing so.

Regardless, account "hacker1001101001" too may be related to bumping services.
If he pretends to be thread bumper than he might be surely owning some more accounts.
I will investigate some more and will update the thread accordingly.
Till that i request the DT members to tag both of his/her accounts.
