It's surely insane to keep 1200 BTC on an exchange, bad to post the same thing again & again and even worse to image edit the official e-mail by Binance (as Binance support team told at Reddit); however, the issue is starting to get "very old". IMO, Binance should've been able to resolve it by now, or at least they should constantly update him on the issue.
They shouldn't because he's already doing shady things like altering the replies. We all don't know the exact details of how it all started but who knows maybe he could be the scammer that's trying to claim the funds. If they speed up the process only because of these posts then Binance might give it to the wrong person.
I'd not agree with that. If I ever had my 1200 bitcoins locked up like that (though I'd never put it all up on a single exchange/account), I'd have literally spammed the whole crypto world (BitcoinTalk, Twitter, Reddit, etc) to pressurize Binance a bit. This DOES pressurize them, a lot of complaints like these can ultimately lead to loss of their exchange volume.
