How Often Should I Revoke Smart Contracts?

How often should I revoke smart contracts?

I need advice on how often I should revoke all smart contracts? Is this something I should do regularly or is only necessary if I suspect I interacted with a potential scam sites or random Nft purchases?

I’ve recently been using smart contracts and remember a post a while back the need to revoke smart contracts to prevent malicious contracts from draining funds. I don’t suspect I have interacted with on at this time but anything is possible in crypto so I just want to be safe.

Appreciate any help you all give me as always!
