Good luck, I'm sorry for all of this speculation and people attacking your solution instead of suggesting concrete improvements to help fight the problem.
There will always be bots, they were here before anubis, they'll be there long after you block them again. Take care of yourself first. There's no need to make a bad day worse trying to sprint down a marathon.
You're doing a tremendous job. On a personal note, I'm not angry or anything, it's just the nature of the process. No hard feelings here. I root for you.
Hope everything goes way better and way sooner than you ever imagined. Good luck & godspeed!
