Plenty of OUT tx:

Upon further inspection, it actually looks like the only transactions they're processing are the ones from their own wallet. The entire TX history looks really suspicious to me.
E.g a very recent TX with some ETH going out: https://etherscan.io/tx/0x5a282187181907995b37c0df1888dfe364...
That being said, does FTX even allow custodial ERC20 transactions? I'd be surprised if they did.
