Yeah d5000, 1miau and bob123 seem like different people enough imo.
I think this has been brought up before as the German board isn't so active so a lot of recent posts and recent topics get pushed to the top so threads don't get swamped very much.
I dont accuse 1meow of anything but he is a merrit source and he has exchanged trust (despite no transaction), bumps for sig threads (to ask for sig sponsor), and merrit extensively with that guy.
