Airdrops on crypto is still can’t solve this no matter how hard they requirements since cheater will always find a way to cheat and take advantage on free money. Ignoring the giveaway is one way to let our mind calm down or just participate but don't expect to win.
I could just do a 500 dollar giveaway, like 10 lucky people wins, and in order to join the draw you need to follow that account, and retweet the tweet as well, and tag 3 people. Why do you think people do that? Because that actually does work and I have done it before. I helped someone gain 100k followers within 3 months before, and it really worked, they were a friend so I didn't get paid, I just helped, and they said I should turn that into a job, it's that easy to me, but people do not see it.
I also share this way of thinking, when some prizes are offered in money, crypto or something like that, and you need to follow, like and RT , it is very easy to get followers , because many people want to win , it does not hurt to get 100usd or an amount like that just continue, like and rt, it's the easiest thing in the world, and although the chances are small to win , it's still there , so it may be that some people say that yes, the bots are the ones that Damage everything because they do that non-organic traffic is created , or that many fake followers are produced , but this does not cloud what contests are where they offer to win for simply doing Things like that , and it is in fact one of the Best strategies to get people.
