Should I limit quantities per customer?

I'm running an online store and want to implement smarter discount strategies. I've noticed some customers abuse promotions by creating multiple accounts or buying excessive quantities during sales. I need guidance on whether and how to limit purchase quantities during discounts to prevent inventory depletion, maintain fairness, and protect my profit margins. What are the strategic considerations for implementing customer purchase limits?
