Yousif Yalda is still up to no good, joining in on fun activities like cost-per-action (CPA) fraud, unauthorized "security testing", and being an Internet tough guy by threatening other people. Below are several posts from Yousif on an Internet marketing forum. They have been mirrored here for posterity.
Yousif soliciting for people to join his CPA scheme: http://forums.digitalpoint.com/showthread.php?p=8965205#post8965205
On a different forum, he's requesting help creating a program to assist in his CPA scheme: http://www.digitalgangster.com/4um/showthread.php?t=57286
Yousif boasting about an unauthorized security test he performed against a webhosting company: http://forums.digitalpoint.com/showthread.php?p=8666245#post8666245
Yousif threatening someone for correcting his knowledge of buffer overflows: http://forums.digitalpoint.com/showthread.php?p=8609011#post8609011
More threats after someone trolled him in his post asking for help writing his program: http://digitalgangster.com/4um/showthread.php?p=1009604
While not as damning as the original post, I think the above clearly show he has not changed his ways. Anyone thinking about hiring him for his "ethical" security services should definitely be familiar with the other activities he uses to generate revenue.
