Coinbase will do the same but I've never heard of tracking that dedicated, only on direct transfers to places that break their terms.
Well, we don't know that yet because Coinbase boots people without a reason and from there they can't do anything but accept no longer being able to use that platform ever again.
Coinbase has much more to lose so it's even more likely for them to pull out their big guns to protect their bank accounts and relations. I'm just glad they allow people to withdraw their coins after being booted.
I can see a time where a breach of terms might result in a penalty that costs you a certain percentage of whatever your entire balance is. This is something not entirely uncommon within the banking space.
