Usually the biggest problem with comment sections is moderation. For example for spam (automated or non-automated). I couldn't find anything about that topic on the site, how are you going to deal with that?
An idea I have is to implement a publicly-viewable ban list. Possibly a file like `bans.txt` available in the public repo which anyone can discuss and add suggestions. This will be a list of domains which Bhread and other instances can reference as an 'ignore' list.
I'm open for ideas. I'm still looking for other options.
