From Fatman Twitter:

As of right now there are three separate things going on for UST holders:

1. A small refund from LFG
2. A token airdrop for the new LUNA (weighted in favour of new UST buyers at a 2:1 ratio)
3. Potential legal action seeking full restitution, more info on this coming (1/2)

All of these plans are mostly unrelated and are happening at once. Getting the LFG refund may not stop you from being a part of the legal action. Getting LUNA tokens does not reverse the LFG refund. I know it's a little hard to follow, so thanks for bearing with me. (2/2)
