I find this a bit too much “black magic” since we don’t know what is causing the delay.

I suspect the delay is caused by a large sidekiq queue or something similar and although the majority is under one second, about 3% is in the range of 0:00:01 - 0:15:00 (one second to 15 minutes).

And half a percent is in the order of days, which seems the kind of abuse we’re trying to prevent. So although this is effective, it would be doing more bad than good because of the amount of false positives.
