If it's not a real deal, don't stamp it. It is not true friends who put their friends in danger, so you don't have to worry about not being able to help.

The regulation and risk of law should be greater than the friendship between friends. All acts are legal, and the person who is instigated to constitute a crime is also an accomplice, and should bear legal responsibility according to the harmfulness of the act.

Therefore, suggestions should be treated with caution, and you can politely refuse. If it really doesn't work, you can directly tell the other person your worries and directly refuse, even if you are not friends.
