Recently, I saw someone going around granting permissions for social mining and fan tokens, feeling that "attention is mining" basically means signing multiple times and leaving more footprints on the chain... But the easiest thing to overlook is the unlimited contract authorization issue. Many people think that as long as they haven't been robbed, it's fine; in fact, not revoking permissions is like not sleeping: just because nothing has happened now doesn't mean your body (wallet) isn't overdrawing. Especially with some old project contract upgrades or front-end domain changes, if a small vulnerability appears one day, your previous "unlimited" access could turn into a door card that others can swipe at will.

There are many tutorials, but I personally prefer those that explain, one by one, which permissions you should keep and which to revoke based on the existing authorization list in your wallet. Don't just hit "revoke all" at once; the experience is too bad, and when you really need to use it, you're too lazy to re-approve. Anyway, I now get into the habit of: close permissions after use, clean them periodically, just like brushing teeth... it's troublesome but peace of mind.
