I agree. All in all, I have joined two, but after my friend, has been victimized by these phishing links and his wallet details stolen, and ultimately, what's in it. I avoided joining in it as to not experience the same. Anyway, the purpose of airdrops is not really to enrich anyone but to have the coin or token introduced in the market, instead of getting coins through that means, which would not give any substantial profit. I would rather get it through bounties, which is my usual method of gaining coins. Although it has its own risks, I feel it is safer and could give more coins for better gain.
