AiLink itself is cool but I it was hard to find a connection between them and the website hosting the airdrop (alidrop.me). No link to social media accounts like twitter on their website. Google search gave me this account: @ailinkofficial. But because there is no link from their website to it it's not 100% sure if it's their real twitter account. Anyway on this account there is a guide for the airdrop which makes me confident it's real. The next problematic thing is their team. It's huge but there are no links to linkedIn or other platforms. Just images with a text. Seems always a bit fake to me. All in all I would take part in the airdrop because it really takes only 30 seconds.
