According to this post, you had 2.1 million views however per above you only pay out 1050 sats for each claim and have paid out 2.7 BTC since December.

Based on the above, your faucet has only been claimed ~257k times. Even if you were to back out 50% of the traffic to account for when your faucet was "dry" (which also makes zero sense if it is actually profiting) then you would have ~1.05 million views when you were actually paying out, and assuming that it takes two impressions to claim then you are down to ~500k impressions that cannot be accounted for why you are getting them.

tl;dr you are lying about either the number of impressions or how much you are paying out or both (most likely)
