I bought 35 accounts from @Jack_Dust website accsmarket. In the first step some accounts did not work, they got replaced. Fine so far. To be safe I let the accounts rest some days. Now, 3 days after I checked them and 90% of them had invalid credentials, can't login anymore. Even the mail adresses are not working anymore. I opened a support ticket and asked for a refund (since he took the accounts back, changed credentials), @Jack_Dust answered the following: That's unprofessional. I don't know why the kid is even allowed to offer his accounts on Blackhatworld.
