What is the default limit for SNS?

Excuse me, could you please clarify what you mean by "SNS" in this context? Assuming you're referring to a social networking service or similar platform, the default limit for various functions or features, such as the number of friends or followers one can have, the frequency of posts or interactions, or the amount of data that can be transferred, can vary greatly depending on the specific platform and its policies. In general, however, if we're discussing limits imposed by a social networking service, these defaults are often set by the platform's administrators and are designed to ensure the smooth operation of the service while also protecting the privacy and security of its users. Without knowing the specific SNS you're referring to, it's difficult to provide an exact answer to your question. However, I would recommend checking the platform's terms of service or contacting its customer support for more information on its default limits.
