* He has 4,000 videos on his guitar website behind a paywall, paying $400/yr (Business Plan)
* His plan offers 5TB of storage, he uses 1.3 TB (from memory).
* Vimeo does not give users access to bandwidth stats.
* He was told he has exceeded some unpublished threshold for 13 months and his account will be shutdown if it exceeds it again.
* He was offered a contract and given 7 days to sign it for $5000/yr and his account would not be shutdown during this period.
On the pricing page Vimeo claims unlimited bandwidth for the $50/month Business plan:
"Unlimited bandwidth (subject to fair use)" and when you mouseover it, a popup says "Users in the top 1% of monthly bandwidth usage (99% of Vimeo users never reach this threshold), may be charged for excessive usage".
So it seems 1% of users are forced into custom contracts that exceed the highest published tier of pricing. I would have expected some additional chargers for exceeding some threshold, not increasing the monthly cost by 13x.
