Guys , we have to do something .
I see a some posts like giveaway tokens for anyone who do some easy tasks and write their info in google doc form .
This is actually scam . Because they invited them to their airdrop telegram or directly joined in a invited airdrop link .
It's make people who scam get more refferal and they no pay for people who do the tasks as promise .
What you are referring as scam would more or less qualify most of the bounty campaigns and airdrops as scams! For a project to be called as scam i follow some basic steps:-
1) Check if the team has pictures and videos of them talking about the project. No pictures and videos of the team means a higher probability of running away with the money with no way to point at a face. Always crosscheck the pictures placed on the website with a reverse image check to ensure that the pictures are not taken from shutterstock or any other website hosting tons of photographs.
2) Check their whitepaper and try to find similar projects or run a search of the whitepaper to find if there is a similarity with the other project and then you can call them out on their thread or start your own with some facts.
Regarding giveaways, that is still allowed. Most of the people refer people other projects with the hope of getting "a little extra for themselves" by doing it.
Some projects put in a lot of effort so you need to do your bit of research and then accuse any project of scamming or not following rules because it might damage someone's reputation if accusations are made without any facts! No one is going to do the research for you if you simply put up a project name and call it as scam!
