Is there a way to report this bot? Find out who owns the bot and reach out to them perhaps? Maybe reconcile your differences with that person? Dunno.
The only bot I actually like is FullTimeBot because there is a human behind it who programs it to upvote people on the list. Like a curation team, but it's bots instead who take turns upvoting the people the person put on the list. We don't pay, we just exist, and that bot will find us. You can inquire with FullTimeGeek more info on that.
And of course I like curation teams like archdruid and Curie because they are real people managing a team of curators. In the case of FullTimeBot, they form the curation team up to I think 75 bots. As soon as they are at 100%, they upvote someone who has nto yet been upvoted. Sometimes I get one or two votes and other times 4 or 5 votes. It really depends.
I'd try to find the person behind the bot downvoting and try to reach out. You never know, you might make a new friend ;) Maybe you got on some blacklist somewhere by accident. I hope for you that the bot stops at some point. You seem like a decent person :) Followed.
Anyone who is says 'I'm really glad your cat died' will only have one kind of 'reaching out' by me...
Reconciliation (in this case) is a dish best served 6 foot under!
lolol
