Hello,
thank you reporting this anomaly, indeed we are aware that, due to a long-standing defect in our accounting code, we have not been taking measures, like stopping measurements, against users running out of credits. This process did not entirely fail, which would have been noticeable to us, but it also didn't do its job properly for quite some time. Ultimately it led to large negative balances in some user accounts (we estimate 330 users).
We are now evaluating how to gently re-introduce these measures, making sure that users are made aware of the situation and are not negatively impacted.
More details will follow soon.

Thank you and kind regards

Francesco Iannuzzelli

Hi,

I created some rather large measurements a few months ago.  I got a
notice at some point that I was going to run out of credits and that the
measurements would be stopped -- something which has happened to me
before.

Somehow, it looks like the measurements didn't stop (or maybe did stop and
were then resumed), and my account balance has gone very significantly
negative before I got around to checking what was going on.  I keep
getting e-mail notifications warning me that my balance is nearly
exhausted, but these notifications (correctly?) state that my balance
is already negative, and will run out a negative amount of time into
the future.

Can I assume this is a backend bug, where some part of the logic for
credit exhaustion wrongly assumes that one's balance is currently
positive, and then never triggers after it somehow becomes negative?

My dashboard page somewhat comically states

Daily credit spending currently (approximately) / your limit: 	7160665 / 1000000
Daily measurement result flow (approximately) / your limit: 	721024 / 100000

I didn't mean to "overdraw" the system or use resources without
contributing resources back; I just didn't realize the cost of some
particular measurements, and had previously seen that measurements
that one's account couldn't afford would in fact be terminated.  Can I
"declare bankruptcy" and get my balance reset to zero?  And can someone
take a look at the credit logic to understand how this credit overdraft
phenomenon can come about?

Thanks!
