But it only asks for the BNB address of the investor. How would these con-artists scam those who just dropped their BNB address there?
If they will redirect you to a fake link then that's the real scam, but anyways, on this one I don't see any intent of scamming at all, but the fact that they almost copied SPACE ID is already a red flag.
Same thoughts, although they can now see the addresses of those users and maybe the true attack is about to begin. They can send malicious tokens to those addresses and once those users interact with the tokens, that's going to be the time that they will be hacked. For the airdrops or even in bounties, it is advisable to use a disposable wallet/address and send only the legit coins after, in your main wallet to avoid any issues.
Overall, whenever you see airdrops like this, make sure that you double-check their official website or Twitter account so that you will not get scammed or whatever thing that they will do just to get your money. Be vigilant because scammers are everywhere. Just one wrong click of yours, and you might lose all of your money.
Legit Twitter accounts usually has a blue check on them. If not, we can also based on the number of followers. Legit accounts usually have lots of followers (over 20 to 30k) and has a small number of following users.
