I completely understand where you're coming from - I ran a similar test around a product launch last year. Went with a small, drip-fed package (likes plus a few hundred followers) just to give the account a bit of legitimacy from day one. The effect was real: a handful of organic users followed after seeing posts with 100+ likes, and both my ads and organic content saw slightly better initial traction because the page didn't feel abandoned.
Two factors made the difference: 1) slow delivery - sudden spikes look suspicious and can throttle reach, 2) pairing it with genuine engagement (I replied to every comment, sent DMs to new followers, and ran a tiny ad) so the algorithm detected real activity. I wouldn't recommend large follower packages - a bloated follower count with no engagement can harm your reach in the long run. Buying likes and views, especially on Reels, feels less risky than dumping followers.
For what it's worth, my experience with my fame com gave that initial credibility boost, and customer support was better than when I tried Buzzoid, Twicsy, or Stormlikes - their delivery felt more organic. It's not a magic bullet, but used sparingly and strategically, it can give you a helpful nudge.
