I think the biggest loophole would be if he holds on binance. In that case he will also get the airdrop 1:1.
As of now, not letting him or any centralised entity back in power is on the top of the list. It is certain that selected accounts will not get the airdrop, how does that afect accounts that get airdrop from exchanges is unclear.
Also, lets not forget the 30 days powered up account voting delay.

I'm very interested to see how things turn out.
