I think OP is counting commenting as being a "participator". I pretty much followed the 90-9-1 rule with my 11 year reddit account (90% lurk, 9% comment, 1% post) and likely will do the same here. I was always very diligent up/downvoting things based on value and reporting violations at reddit though, which I think gets calculated into their engagement metrics, unlike at Lemmy if I am not mistaken.
