I guess it might help - just to dissolve your normal activity with other types of things. You can also create posts without links, like, ask something in r/AskReddit or join a discussion of a series you like - series often have a sub.
As they say:
It's perfectly fine to be a redditor with a website, it's not okay to be a website with a reddit account.
I personally try to be active in different ways but get too tired with online.
