How do I add a disruptive commenter to a killfile list - and never see his/her nonsense ever again, without moderating every comment, being published?
This would be a popular feature - if it could be provided, in any way that would achieve results.
Using a killfile, to filter disruptive / malicios commenters, is not a likely possibility.
Anybody who does not want to be identified can comment as desired.
It is not possible to reliabily identify a comment publisher, who does not wish to be identified.
- Blogger / Google identity.
- IP address.
Disruptive individuals can't be identified, with any chance of success. Anybody who wants to publish comments can do so, using multiple accounts, and / or IP addresses.
Both Blogger / Google accounts and IP addresses can be easily cloaked.
Using either multiple Blogger / Google accounts - or IP addresses - is a trivial exercise for anybody who is determined enough to persistently publish unwanted comments.
Given the impossibility of identifying people who don't provide effective identification, Blogger is unlikely to provide a feature that would accomplish nothing - and possibly interfere with legitimate commenting.
The only solution for blocking unacceptable comments will always involve collaborative, fuzzy filters, trained by each blog owner.
Some #Blogger blog owners would like to use a killfile, to filter unacceptable comments. They don't understand that anybody who wants to persistently publish disruptive or malicious comments can easily mask their identity - and make killfile use an exercis in futility.
