Root cause of all the problems here is Jamal. He is not a good manager. Just to earn few hundred dollars, he promotes scam. And later says I wasn't associated with them. He should check first that project is legit.
Since he was the campaign manager, we only have right to ask increase in bounty from him. It is his responsibility to extract those funds. If he is unable to do so. He should pay from his own pocket.
He should have made terms of bounty clear with their team. I think he too should be given negative trust.
Earlier I wasn't in favour of giving him negative trust, but after I saw his previous bounty campaigns, it is clear that either, he only chooses scam projects or scam projects only choose him.
I would request everyone who has suffered due to this, to put a negative trust on Taas profile and Jamal profile until they pay the promised amount.
Jamal,I give you two options,
1: pay me the right amount of bounty
2: don't pay me anything and I along with some others will give you negative trust
