I got a chuckle out of that too.
I think there's a lot of commenting going on (primarily positive) any popular post, which users are just fishing for upvotes. There's been a huge surge of it on my posts over the past couple weeks.
I suppose they have a better chance at getting upvotes on a post with visibility as opposed to one without?
might be it, though i don't see much of them getting any upvotes, had they commented on chainbb at least they would've had 16 cents (-15%)
