They are both a waste of time, most of those fake programs are out there just to steal your personal information and sell it to criminals on the dark web.  Do these things and it is very likely you will be the victim of identity fraud.

When you see in every spreadsheet bounty, why every member join social media bounty always get low rewards ?
But in Airdrop their rewards is enough for their task.

I see in bounty group there are many people who join social media bounty rewards is under airdrop rewards.
$1.8 for do facebook bounty but every member who join airdrop get $5. Is enough for bounty who always do task every weeks ?

This is my opinion why airdrop is more profitable than social media bounty

Task for Airdrop is easy than Social Media Bounty

In Airdrop, you only need to join their official page and join form. In Social Media Bounty, you must create,share and like their official page. Most of Social Media bounty must share 5 post and create 2 post.

Social Media Bounty makes more post than Airdrop

To join Social Media Bounty you must make Proff of Authentication then send your bounty report every week. But Airdrop is simple than Bounty, you only create Proff of Authentication

Most of newbie always join Social Media Bounty

Every newbie who try bounty, always join social media. If that bounty is only 4-6 weeks, their rewards is enough about their task. But if in bounty is 8-16 weeks. Social Media Bounty user is more do task and their rewards is too low.

if you participate in social media bounties that do limit participants, I am sure that social media bounty will be more profitable than airdrop, only now that no one does it like that so Airdrop can still be profitable from bounty social media but it also depends on the airdrop project itself.
