<div>Hello Liviu!</div><div> </div><div>I am sorry, i totally missed one important thing - serial forking)))</div><div>I.e. i had 52 records in accounting, but several of them leads to one call.</div><div>As a result i had exactly 29 calls before fraud module became block subsequent calls.</div><div> </div><div>About counters reset i understood.

Keep in mind that all fraud_detection module stats are per-user counters, and not global counters. If they really were all made by the same user, please let me know and I will double-check my tests.</p><p>The "cpm", "total_calls" and "concurrent_calls" reset either on an interval change or at midnight (new day ahead). This leads to a possible undetected abuse of up to 2x your provisioned "cpm", "total_calls" or "concurrent_calls", if the malicious user places "limit - 1" events before the reset, followed by another "limit - 1" events past the reset. If this is too much for you, then your provisioned limits (thresholds) are incorrect, and you should simply cut them in half.</p><p>Best regards,</p><pre>Liviu Chircu
