“Are face scrubs good for acne?”

If the patient uses the gentlest of gentle technique they can at least not make things worse. Most of the time the abrasiveness of scrubs will make things worse instead of better.

Unfortunately, they are not typically good for acne, or for that matter, any skin except for perhaps the most, most oily skin. And even there, I wouldn't necessarily recommend them. Scrubs basically dry out the skin, and when the skin gets too dry, it becomes intolerant to acne medications (which also unfortunately dry out the skin a bit, especially if not used properly). And the acne medications are the real weapons against acne. Short answer: forget the scrubs and instead use gentle cleansers and proper anti-acne topicals.
