is there a way to find/see renewal transactions for a specific ens name?

building /cabin (cabin.city). founder of LBRY.com, odysee.com, vibe.camp, /farcon. more at grin.io

Can you search the target addresses transactions for the ENS contracts and infer from there?

Ahh. If you swapped it. The ENS contracts should still show record of the target address having received something. Maybe?

I think the renewals are coming from a diff address than the owner

or maybe i misunderstood what you're suggesting?
