seven years in, I remember when Voluum and BeMob felt solid, reliable. Now? I tried RedTrack last month, thought it was a till I saw the nightmare reports of data leaks and fake traffic detection. Numbers don't lie - my ROI tanked after I caught the scam signs. Old days you could trust tracking solutions, now you gotta watch out for the shady stuff or get burned. Network reviews help but you gotta dig deep, check the payouts, and cross-verify data. Traffic source is king, but without solid tracking you just chasing ghosts.
