No, The two would not have been related
Infinity free isn’t inteded for file shareing or streaming. So this is more likely the problem.
If its a permenant suspension then you’ll be able to raise a help ticket in the client area to ask for more information, and request a reversal of the suspension.
If its a temporary (usually 24 hour) suspension, you’ll just have to wait it out.
As a business man myself, I would not entrust me entier business to a free hosting service. End of the day, infinity free is great, but you get what you pay for. As for your hard work, thats what backups are for.
–further comments–
I’ve just seen KangJL’s comment. And would like to echo what’s already been said. When you set up a site, you take full responsability for that sites content. If you choose to host an illegal steaming service, you are liable. Neither infinity free, nor IFastNet are going to be prepared to do that. so unfortunaitly this is your own doing
