Another trick could be to increase hype. Original author could've done that, for example because they always planned to burn 1k USD in BTC on this for whatever reason.
And then there's the trick to hope others follow, after which he, ehh, magically takes the money. That's a bit akin to ICO scams.
Can I prove any of the above theories? No. But the author cannot prove their motives are sincere either.

i picked the wrong profession
Made my tax audit rather painful.... "I posted a joke on the internet about binary numbers not being worth anything and someone gave me $10k of bitcoin that I'm now declaring - is it income for the work of writing the joke, or a gift? The sender likely didn't know who I was, and was likely overseas but I cannot prove who they were or which country they were in".
If that were true, and someone can hack the server for less than $500 of tokens, its an easy profit.
For $500 he can look in the logs and find all manner of new exploits, or new deviations of the existing ones, he can then sell for thousands. Clever business model lol
These projects would be more interesting and ethical if the current and historical logs were instantly put up somewhere public in real-time for anyone to observe.
Regardless, I'm guessing the smart hackers aren't going to bother.
