it seems you're the one who is protecting/encouraging them instead of reporting them to moderators in the first place.
Thieves? Are you getting scammed by yolodice's users? You need to inform them by sending a pm to ethan or email support with valid proofs. Anyway, if you are getting scammed, something like you give a loan to other user but he/she do not pay back it then it is basically your own fault. Bear in mind to avoid lending some money to other users, unless you know them personally. It does not reduce the reliability of the site, we cant deny the fact that online scammers are almost everywhere. Be careful.
I have proof. I have submitted my proof. Despite this, no action is taken. In this, the number of these people is increasing.
what kind of actions you're expecting from mods?
you're thinking like banning him permanently could solve this, but the thing is there are chances that he would create another brand new account and repeat the same thing.
in the first place, the site states that they do not involve/encourage loans/loan-dispute between users. but you loaned him on your special interest instead of reporting to moderators.
better get over this and move on. from next time better report them to any of the moderators instead of entertaining them, that is the only way one can prevent them. spamming this thread over and over again about it won't help you in any which way.
