(this is the only already public information i can give to prove that ZaynThatGuy owns D3ad, there is more but i'm already being blackmailed to keep quiet)

D3ad likes buying popular free shirts, but D3ad also randomly bought a free template shirt by ZaynThatGuy.
Zayn has practically no activity, and of all of the other free shirts with the starter Polytoria template D3ad could have bought, they chose that one by Zayn.
