Bleeding $1,200 on a DSP retargeting test that dead-ended in month two

I burned a full week setting up that fancy cross-device retargeting on a $50 CPM and the algorithm just served my ads to three bots and my own boss in Phoenix, so has anyone else seen a platform quietly kill their budget with zero conversions, or did I just get the unlucky account?

Ran into the same wall a few months back with a prospecting campaign. Cut the daily budget in half and threw everything into one narrow audience based on past site visitors who actually added to cart. Those conversions finally showed up around week three, but the platform needed way more time to find the right people than I expected. Also turned off every placement except mobile in-app because that's where the cheap clicks were hiding. Platform kills are real, but sometimes the fix is just shrinking the net and letting it cook longer.
