What is the maximum size limit for SNS?

I'm curious to know, what is the maximum size limit for SNS, or social networking services? Is there a cap on the amount of data or content that can be uploaded, shared, or stored within these platforms? Understanding the limitations, if any, can help users plan their content strategy and ensure they stay within the guidelines set by the service providers. Additionally, it's important to be aware of any potential constraints that may impact the functionality or performance of the platform. Can you elaborate on this aspect of SNS?
