Proof of what? The proof that Ris88, aisyah88, Ais08 and Dey90 are absolutely different people accidentally participating together in campaigns (especially when they join them one by one), and quite by accident collecting tokens in one purse? I do not need such kind of proof. One fact of transferring tokens is enough to determine that accounts are connected (not considering how similar your nicknames are). Especially since I'm not a DT member
