what about people are unable to pay for those information? What about people who are not famous researchers?
Aren't they worth to get those information ?
Don't take offence, but what your are planning looks only like another way of making money than a contribution to security.
I already share info with many independent security folks that I trust. They have access to a repo of malware samples, and I don't expect anything in return.
What happens is during the course of my blog or conferences I get to meet people, we chat and such and if the relationship is good, I open up the gates.
I find it important to establish trust in this industry. If you open up your service to the world, you have no control over who is going to use the information. You'll have people that steal your hard work and take credit for it, or worse use the info in their product and make money off your back without even saying thank you.
By the way, I'm not a famous researcher
