You have pages and pages and pages of sent feedback, you are telling me you went through all of it and removed all of the negatives you left for shitposters How long did they take you?
Without automation, it would take quite a bit of time. You can't delete sent feedback from your own profile and have to navigate to each individual account.
Assume that it takes 6 to 8 seconds per account (page load and finding
your feedback). I believe The Pharmacist and I had hundreds of sent feedback related to spam. Considering the amount of spam that you could find in those days (as well as currently) it could have easily surpassed 500 different accounts.
Which is equivalent to 50 minutes of purely going through your sent feedback.
