Stayaway from connecting your wallet to multiple garbage Sites people Maybe check the project first research its community and check the backers Most project dont ask to connect wallet to collect airdrop just like that. If you follow and read these crypto project I think airdrops comes naturally So dont fall victim into clicking useless links
I used alternative wallet address (i created to specially for airdrops campaign) if any project will require to connect my wallet in their website,
but first of all i will try to find out their all of social media accounts then i will recheck to detect it real or fake project.
