for them all negative trust will not affect anything because they only want free coins and hope to be listed in the market, other things will not matter

Because they just wanna instant 500$ in airdrop dont care about scam project and not research before joining airdrop
it doesn't make sense for an airdrop to give reward 500$ by just doing a very easy task
strongly agree if at the moment it feels really impossible with a prize of that size but if it stands in 2017 it seems like a gift of that size is normal especially when it was more simple but more vulnerable to spam
