I wouldn't want a feature like that. The easier it is to take part, the more people will do it, and the smaller the slice of pie you will receive. I personally look for airdrops (and bounties) that require a little bit more effort or are a little complicated, it increases my chances of making it worthwhile. I definitely don't bother with the airdrops that offer tiny amounts in exchange for increasing amounts of your data. Every bit of data you provide is worth money to any company, so consider what it is worth before participating. All the best.
