What is the maximum SNS topics?

Could you please clarify what you mean by "SNS topics" and the context in which you're asking about the maximum number of them? SNS, often short for Social Networking Services, refers to platforms like Facebook, Twitter, or Instagram where users can share content and interact with others. However, the concept of a "maximum number of topics" isn't inherently tied to SNSs as a whole. If you're referring to a specific SNS platform or feature that has a limit on the number of topics or categories that can be created or followed, then the answer would depend on that platform's policies and guidelines. For example, some forums or message boards may have a limit on the number of topics that can be created in a certain time frame or within a specific category. If you're asking about a general limit that applies to all SNSs, it's important to note that each platform operates independently and sets its own rules and restrictions. Therefore, there isn't a universal "maximum number of SNS topics" that applies across the board. If you could provide more specific information about the context in which you're asking this question, I may be able to give a more accurate and relevant answer.
