More to add on this thread. stay away from twitter airdrops. Majority are scams. they are paid bots trying to gain more followers and attention. the best you can do is stick to bitcointalk forum for better infor on new projects and what it stands for.
Already tested that but luckily I'm aware with that scheme and luckily the one got caught on my end is the email which I used for low tier exchange which is no balance stored.
And people should need to learn this information since even up till now there are so many people joining this no value airdrops and if they don't think smart for sure in future they will encounter a problem in future.
