Oh, I understand... it's sometimes 3-4 days before I come back and check all the comments, and respond. And no, I generally do not upvote or comment on spammy comments.
I don't get around to others as much as I used to... in part the result of having an "active" following now. If I create a post and it suddenly has 50 comments, it takes a lot of time to take care of everything. And I DO actually "have a life," too!
