My like button is on the fritz as well, for quite some time now. I know respond with this: "Since my upvote has been disabled (by the FBI directing the Substack minions), I'll say thank you, in person (maybe we should all have our upvotes disabled, if it encourages direct human contact, instead of the substitution of a sterile 'click.')" --- I'd complain to Substack, but then within ten days I'd end up on the FBI Most Wanted list.
