I mean sure, there are various 'immoral' uses for it (like doxxing), but there are also many good ones. Such as:
1. Working out who wrote a bunch of anonymous reviews on Amazon or other such sites, which could be used to stop fake reviews. You actually mention this usage in your article.
2. Being able to identify troublemakers in a community (such as a forum or a social networking site). I'm sure a lot of administrators would love to know if that suspicious looking new guy is the alias of a banned troll from a few weeks back (posting through a proxy server).
3. Literary analysis, like working out who wrote many anonymous works of fiction. Or as someone said below, determining which parts of Shakespeare plays were actually written by Shakespeare.
4. Crime solving. If it works anywhere near as well as you say, it could theoretically help unmask the Zodiac Killer, or perhaps even Jack the Ripper (if any of those letters were real).
All the uses above would be a net positive for humanity, and would be great possible uses for a deep learning tool like this.
Don't let the worries about its usage by 'bad' people overshadow the good you can do by releasing it.
