That excuse doesn't cut it given this community account only in the past two months reached 1k HP and already has 175.42 HP in curation rewards. Almost double yours.
My personal account has just under 5 HP in curation over the past 30 days and yours is just under 2 HP. And you have more HP than my personal account. So really, you're making an incredibly large sum from your posts and just rarely ever curating anyone.
You can definitely do a bit better.
