Faucets gave me my first cryptocurrency so I can never admit they are dangerous or even risky? There is no risk for users. Users should simply check the website online for virus using sucuri site check before using it.
https://sitecheck.sucuri.net/If the website redirect you to another page (e.g shortlink) then
1. don't click anything
2. Check the new landing page for virus using sucuri site check.
3. If it is clean, then continue and earn from the faucet.
Some Faucets don't redirect users. I recommend such faucets for users. This Faucets are not dangerous, just use it with caution the same way you would browse a new site.
