A community pool has to be spend to compensate for users who locked their USTs in terra’s dApps such as Pylon, Astro and so on.
During the previous disaster from 7th may to 13th may, some of UST holders could not sell their UST becuase their UST were locked in the terra’s dApps. Therefore, their USTs were snapshot for the pre-attak UST case, meaning that they are deserved to get airdrops in the genesis block of Luna 2.0. However, as Woojin, CEO of the Pylon dApp, have confirmed his tweet and telegram  , TFL devs made mistakes for excluding these holders. Thus, they get no airdrop until now. We should consider this issue for the mercy.
