I've already gotten an ofm email earlier this year for an actual legit return.

Did you question It at the time of receiving the email?

Given It was a legit return and assuming It didn't trigger any suspicion, you're well within your rights to dispute It.

It was my first ofm email, took a while to figure what it was and why.  CS would not comment on it when asked. Then I figured out it was likely a high value item that we were having issues scheduling a delivery date so I told the courier to return to sender.  Probably skewed my return ratio.

Then you'd need to accurately calculate the dry Ice sublimation time.

Wouldn't I just have to be close to the weight at the time of drop off at the post office/courier? Once they accept it, it gets weighed and scanned. When it starts to sublimated sitting in their warehouse shouldn't be an issue anymore. Unless you're thinking that calculations are for the ice should have disappeared before it before it arrives at the final destination.
