Well to tell you frankly, after UNISWAP airdrops happened a couple of months ago, scam projects increased more here in cryptocurrency, in fact,
it was scattered and posted in the social media such as Twitter, Facebooks and Telegram and even until now they still looking for a victim and UNISWAP still their main tools of course for this things, so let us be more careful anyway.
Newbie are the most vulnerable to this type of fraud because they don't know more about the fraudulent attempt made by certain individual. I have received an email on behalf of Uniswap some time ago. They offer a 400 UNI airdrop, I don't think this is legitimate as it is very clear that a scam is being tried simply because the sender of the email is different from the Uniswap site. Ignoring these email and offer is a sure way to avoid scam. Try all newbie to be careful and ask question before they decide to enter the platform especially if they want to invest.
