I didn't try social media campaign because of the work load of reporting every week which I don't even know how to get the links, so maybe this time I will try to join with my twitter and facebook. I have however seen some complains about scam ICO which are common in bounty platforms, I guess if they are also in the bitcointalk forum, people will investigate them.
Yes, social campaigns now only bring about 5-10 $ 1 campaign in 3 months. If you do with large numbers of campaigns and nicknames you are eligible to receive max stakes. It's not bad either
