You could do ransomware, you should make them do a survey instead of pay money.
If you have upwards of 10000 slaves you could bitcoin mine.

Thanks bro! Are you aware of any good adware? And, should i use sharecash or file-ice(pending verification)?

Use shrinkonce it offers instant payouts. You get like $1 a survey.
