Earlier quoted context omitted.
You realize how poorly your comments reflect on your product, right? I'll certainly never support Tarsnap after reading this garbage.
I don't agree with cpercival's comments, and I am quite saddened by the loss of Steve - more so than I would have expected. But it should be pointed out that the comments in no way reflect poorly on Tarsnap. It's a fantastic product. (other than the fact that the account balance alerts only consider storage used, not traffic charges. Grr.) edit: Downvoted already? For being a satisfied customer? Really?
I wish I had a good solution to this -- but it's impossible to predict when someone is going to be using lots of bandwidth, and alerting based on the current total spending rate had a very high false positive rate since bandwidth usage usually spikes for a single day and then goes down to a small fraction of the storage cost.
The downvoting is probably for being off-topic.
