Social Networking

This situation calls for some research. My suggestion: ask a selection of your members what posts they read and what they like or share (and why or why not).
Just visit the club and discuss it with everybody you see.

For example, it could be that everybody reads all 5, but shares or likes only 1. Or that nobody reads anything because they aren't following it. Or that nobody shares because they think other members see it also.

If, say, nobody follows it on Twitter, then why do it. The local newspaper might be useful to reach non-members with important news, but if everybody already reads it on other media, only use the local newspaper for really important stuff that's relevant for non-members also.

Social media platforms can benefit businesses by providing an additional channel for customer support and are essential for building brand relationships. If your business is present on multiple networks it is easier for you to keep track of what is being said about your business and respond accordingly and in real-time.

I think, there has no problem with this type of post. Because Different Social media have different Traffic, But your business or target same. So I think you can do this.
