The Venezuelan student scheme shows a good way forward for future airdrops, a small amount of USD value can mean a lot to students in countries with low exchange rates, maybe target a campaign to students in Africa, South America, South East Asia etc if that went viral could easily get loads of new users, sort of like what Facebook did, but target low exchange rate countries where 10 USD is worth jumping through some hoops.
Verifying students is probably quite possible too, avoid sock puppets.
It's good approach to allocate Byteball airdrops to Venezuelan, particularly students and most vulnerable groups of locals there (pregnant women, elderly, etc.). It will be good for both those sort of target airdrop receivers, Byteball project, Byteball community.
Byteball popularity will be increased significantly with such massive airdrops (if available).
