spike is an starfish, but I don't support this drama.
you're dramaing someone for the purpose of BL. We're supposed to make servers to share with people. So what if he makes his own? Good for him. Maybe he'll get more players than you?
Seriously, SOMEONE was bound to copy you. If I host a MERP, I hit 20 players, within the week there's 10 other merps.
If I host fortwars, there's 4 others. If I host a city build, there's 7 others.
So what if he copies you? What's the worst that happens? You split the playercount? Perhaps people go to his first, realize he's an ass, quit then come to you? You shouldn't be concerned with getting credit. People will use and abuse you as long as you are alive. They don't matter. What matters is, how are you going to go beyond what they can promise. See, he could take your idea, your build, your events, your minigame settings... But not you. You can create a totally different environment. Something friendly, something warmer and inviting, something that BRINGS players.
No support. Sorry. The game was made for sharing, if you don't want people building similar ideas, don't play on multiplayer or don't talk about your ideas.
