How did he even manage to do that? I mean, I would understand if your application was the last in the thread so he just c/p your application and changed the details but it was nowhere close to his. Weird..
Anyway, good to see that Shasan started asking for signed message before approving loans.
It might be a common mistake of copy-paste. But I doubt that as while I have mentioned to sign message the user has tried to say the wallet has not been changed as the wallet is his/her own (just my imagination of, it might be right or not).
