How to spot this (Free airdrop claim asks for a signature)

A "Permit" signature costs no gas but authorises spending — drainers love it because it feels harmless.
Unlimited spending of your USDC, for a "free" claim.
Never expires.

Remember: A free claim that asks you to sign unlimited spending is a drainer. Read what you sign; reject anything that says "Unlimited".
