You pour your heart and soul into a site. You manage to get it off the ground, and it's awesome. There's nothing better than a site that's active, that everyone enjoys.
Then your activity dwindles. Real Life kicks you in the balls.
You notice a member has 'borrowed' a ranking system you developed from scratch, to use in a different genre site. Whatever, it's not that big of a deal. They changed it. It's not a carbon copy.
Your site dies. Everyone's real life kicked their ball-sacks and everyone's just kind of, poking it with a stick.
Go back to actually be dutiful, close things properly, and there's an advertisement from an old member. Catches your eye. You read it and think "Huh, this sounds just like THIS EXACT SITE." They even slip something about 'Inspired by [yoursitename]' into their advertisement. What is this tomfoolery?
A quick browsing of the rules, and they are SO DAMN FAMILIAR.
Because they were STOLEN. WORD FOR WORD. FROM YOUR SITE.
That's not all! Your Plot! Your information pages, it's all on THEIR SITE.
What in the good name of Grace are you supposed to do? How do you handle this? Am I wrong for being unreasonably irate?
