Please follow the proper format, give some concrete & verifiable evidence.
Why're you posting on your newbie account? Too afraid to risk your main account because throwing up some scam accusations?
You won't find any concrete evidence. OP posted how he thinks about automated bounty platforms so it should go down in Altcoins Discussion or in Marketplace (Altcoins).
@OP
0 transparency doesn't means they are scamming but gives them the chance to manipulate calculations for their own benefit (which is hard to prove unless you have the sheet) . You cannot determine that it is also the sole result of failed ICO . I don't like automated bounty portals much but yes I do agree that use of such should be avoided.
