Because it's not with 1 more GB space storage for saves/screenshots or chat rooms that you will have premiums.
I was just trying to help you with those ideas, but as I see, better saying nothing.
I believe his point was that all of your suggestions involved downgrading the existing performance or user-friendliness of the service for the everyday RTB user.
There are ways to entice users to pay for the premium service without hitting them over the head with frustrating usage caps, wait times, and Captchas. I understand how one might compare the RTB service to existing download sites but it is important to note the differences between the two and why most of those sites implement user restrictions. Typical download sites, such as Megaupload, must serve thousands of customers per day which generates a considerable operating cost and the sites must make a profit off of it's premium subscribers. The company is under tremendous pressure to push users to purchase the upgraded service and so add annoying wait times and usage limits to non-paying members. Captchas are usually just there to stop bots from abusing the service.
RTB, on the other hand, is a much smaller service, isn't a profit-making entity, and doesn't usually fall victim to abuse by bots. It services a community that has little, if any, ability to pay for its operation, and is operated voluntarily by Ephialtes at his own expense. He has little to gain by restricting his service as your suggestions imply he should.
On a slightly different note, I've had no luck finding a game-server-hosting company willing to host servers for Blockland. Understandably, I don't think they see it as a profitable use of their time. So, I'm still interested in RTB offering a hosting service.
