* Is there a sticky explaining the differences of airdrops vs bounties vs signature campaigns?
The biggest difference between airdrop and bounty is that you do not have to spend a lot of time to get the free token but with low value, bounty, and signature, you need to invest a lot of time, and profit is very high if you join potential ICO project.
* Do they favor my status (Jr Member I think I am) ... I know that higher statuses earn more at this point
Yes, with the higher rank, the number of skates and tokens you earn will also be higher.
* Can you participate in more than one?
No, with signature campaigns you can only participate in one campaign at the same time, and other campaigns like social can use multiple accounts to join one campaign.
* If you post here everyday as a habit, what's the level of extra effort involved in participating in bounties and signature campaigns?
Posting to participate in the campaign depends on the rules of each campaign, you need to read the rules carefully and comply with, if not comply, you will not be counted skates.
