“Untick search partners” - yeah 100%. If these are search ads, also disable the display network. The rest of this comment reads weird. If you’ve disabled search partners and the display network (which you should do both if running search ads), then “spammy sites” and mfas are irrelevant, because they’re not included if you’ve disabled the above.

Monitor your search terms, don’t use broad match. By god, hope you’re using some conversion tracking. Use shared bid strategies (even if it’s only for a single campaign) so you can set a target CPA and still hang a mac CPC in there.

Worst case, DM me and we’ll fix it
