Looking up your name on google for similar cases of this, I found you did this on two other forums.
Both of them seemed to be created by a single member, but if that's who you think started this, he didn't create the topic.
Otherwise, I see no reason why you'd ask to take it down. All you're really ending up doing here is alienating fans of your work.
He isn't saying he created the hack, and I don't think anyone here thinks he would, given RPG's trend towards starting things but never finshing them.
Although you hypothetically have the right to do so, taking down every unauthorized mention of your hack will only hurt it in the long run.
In copyright law, things like this count as fair use: showing someone something while giving full credit to the author.
I guess in the end it all comes down to your opinion. If you don't want it on here because you see a slew of hacks which you consider inferior, then do so. If you don't want it on here because you want to know in case anybody decides to insult or meddle with your work, that's fine. But coming in here, no holds barred, just asking for it to be taken down isn't going to get you anywhere besides cross feelings and escalating drama.
Now, could you please explain why?
