How to get free Stacks?

Could you please elaborate on the methods of obtaining Stacks without any cost? I'm particularly interested in understanding the various ways one can acquire these cryptocurrencies without investing their own funds. Are there any specific platforms or activities that reward users with Stacks? Additionally, are there any specific conditions or requirements that need to be met in order to qualify for these free Stacks? I'm also curious about the potential risks involved in these methods, as well as any suggestions you may have for maximizing the number of free Stacks one can acquire. Thank you for your insights and guidance.
