I have been using Darwinbots for several years, probably all the way back to 2010. In all that time, I have never seen a single robot teleported into my sim from the internet. Maybe I've gotten unlucky, only running sims when IM was down. Maybe I've never managed to configure my settings properly. I'm relatively certain, however, that IM is simply broken.
As far as I can tell, there is no evidence that Internet Mode even exists! For all I know, it might all be a conspiracy or scam!
The internet teleporter always sucks up my good robots, but never gives me anything in return. They are simply deleted, or otherwise cast into the empty void that is the internet. It's like a black hole, more than once has my "king robot" fallen through the event horizon.
I really hope that we can find a fix for IM, hopefully sometime soon.
