I personally don't believe you can deliver unlimited and offering unlimited packages can open you up for abuse, but that's already been made clear and it's your business model not ours
It's not our place to judge your business model, if you feel that paying for other people's web space with nothing in return is a viable long term business model, that's down to you, however experience gained from many years in the market and many, many more on the Internet would suggest that you're not the first and won't be the last.
What is our place though to help our members and guests be clear on what they can and can't actually buy / get as freebies from the forum.
The thread has not been delete in the interests of anyone researching your offerings as this may be found at a later date in a search engine and should help with their decision making by providing the pitfalls of unlimited offers.
