It depends what’s the clients goal.
IG growth solely, engagement growth without harming trust score or product sales? Short term sales, long term sales and building a brand? I would use different strategy depending the product price even.
F/unf is ok for sales to keep a steady stream, but if you manage to get reach and hit explore regularly, what would be difficult with just f/unf you can sell much bigger numbers.
I used f/unf for quite a while and with current changes it’s not as effective as organic reach and high trust score.
It also depends who the client is, some types can get away with f/unf even caught, for some types it would harm the image. (Long term relations, subscriptions?)
