A/B Test: Does using fameviso to buy followers and likes actually improve Klaviyo form conversions?

We are having a massive debate at the agency right now over the empty profile conversion killer. Normally when cold paid traffic hits a brand new ecommerce site and spots a blank IG profile, people instantly assume the brand is a scam and completely ignore the Klaviyo popup. We just had a client go totally rogue and use fameviso to buy followers and likes just to pad out their social proof before our campaigns went live. The crazy part is our signup form conversions actually shot up from a miserable 1.2% to almost 4.5% on the exact same traffic source! I am honestly completely torn on this whole situation. Has anyone else noticed this direct correlation between artificially inflated social proof and email optin rates, and do you ever secretly tell clients to pad their numbers just to pass that initial trust test or does that just wreck the list quality in the long run?
