>I think this place might as well become my new territory
No. Thats bullshit. Right off the bat.
>I'm pretty pro with converting
A little self confidence never hurt anything, but thats just stupid. Even if you think you're, "pro," you ought to have a little humility.
>, don't you damn well try and steal my ideas or works without crediting me
A resonable request. REQUEST. You don't demand shit from /tg/. And if his material was worth crediting, I doubt anyone would steal it as his own because everyone else would know it wasn't. Thats just stupid.
So, lets recap:
This faggot posted, claiming our board as HIS, then proclaimed, "he was pro," and we could ask him for help if we wanted, and then demanded we show him proper respect by not stealing his work. This last bit really isn't unreasonable except that he DEMANDED it.
tl;dr fuck off, rage is justified.
