I would suggest contacting the devs for Ankhbot… you might appease them to do an update for the API update, even though they announced quite some time ago that they were ending active development on that bot… my suggestion, find another bot that has this feature that won’t stop working once v3 API is totally offline (I personallywould recommend PhantomBot, but don’t know if it has the account age feature or not)
EDIT: it does have the functionality
