A negative rating right now is completely useless and will be disregarded by the supermajority of the users (the same way that neutral ratings always have been). I'd actually advise against leaving them to save yourself the time and trouble; just skip straight into scammer flags.
Neutral tags serve a purpose. Some examples from the feedback I left:
See Reference link for a signed message that proves ownership of the account.
Shasan has a temp ban. If you need to contact him, use other means.
Leaves fake red trust to spam hunters after theymos wiped all yobit signatures.
I tagged this account as being stolen on August 7, 2018. It has been recovered by the original owner on February 22, 2019.
These have nothing to do with scams, it's more like adding sticky notes to a user. And indeed, they're intended to be ignored by users.
From what I understand, you can only create Flags when you've been scammed. That means negative ratings still serve a purpose.
I like the much bigger warning on topics created by a Flagged scammer! It also makes sense to only create Flags for users that scammed you personally. That means it's really worth the extra effort, and it shouldn't be used at massive numbers. I've checked all my feedback, and only one person (with 4 accounts) really qualifies for a Flag. Can I request Flag support here?
I have over 1000 Negative feedback sent to abusers and with the new limited feedbacks for page on trust profile
https://bitcointalk.org/index.php?action=trust;u=1339716 is a nightmare to navigate them.
Can you please rollback this page as it was before?
For people with a lot of feedbacks is impossible so search something there.
I'd like to see at least 1000 ratings per page, that's high enough to make searching easier, and low enough to load the page quickly.
