If you join a team and work once every 3 days you can have your list ready and comment a day and spread some joy. Since you already comment there won't be much difference it's just in name of SC so don't forget to leave yours. It would do those who are always forgotten good. I had great chats, happy people but you also have to explain you are just that sc for 1 month and the next one doesn't care about reading them and that is a problem. Commenting is not engagement. It's leaving a message behind.
Engagement starts if the message is answered and we keep talking.

I believe you already give a lot to the platform.
Does the platform give you anything in return? If you still stick to 3 posts per week you already made something clear about how you want to work.

A lot here is long term commitment but a hobby should not break people.
