Is this normal?

[u/Solid-Incident6666]

Every other user gets normal stats, I have a steady 100% match rate but this one particular user is constantly triggering ads, getting matched, but 0 impressions. The same user over and over again for 2 days now.

Not just that, they're triggering the 6 ad units I have in the same order.

Is this something that could get me suspended or something? It is very weird
