[@71452K] I would not consider it [i]unethical[/i], because that'd imply there are ethics involved when it comes to writing stories and, as my experience has shown, ethics are something best left out of writing all together. If ethics were involved we would not have stories about things that are taboo, i.e. holocaust, or something. 

At the very least I'd consider it a bit strange and a bit rude, but whatever, it's not like that doesn't happen on a permanent basis on this website, and other websites. 

However I also believe that if you're not posting something under your own recognizable name, you shouldn't post it at all because it removes credibility and so forth.
