BTCAndres on X (not sure if it's the same as @BtcAndres here) did a thing where he went tried to figure out how many addresses Tether froze in the last week.
The way he presents his findings is a little confusing, but it looks like maybe the answer is 74?
Whatever the case, I like how he phrased it in the first tweet: Tether on your hardware wallet can still be frozen.
