After internal discussions, we have decided to make the list of blacklisted domains public. Please leave a comment if you think some domain from the list doesn't deserve to be blacklisted.

There's also a more radical option on the table - get rid of all current blacklists, and rely almost exclusively on up and downvotes for content moderation. In this option, automated blacklists would serve only as a last resort - in cases of bought votes, massive spamming, brigading or similar attacks that overwhelm organic voting from members.
Please make a comment if you feel strongly about this approach, whether against or for.

The current list is here.
edit:
Alphabetically sorted list of blacklisted domains, one per line

edit2: to clear misunderstandings - this list is from before the split and secret blacklists are supported by r/ethfinance's mods. This post is about potentially getting rid of them altogether.
see this comment from ethfinance moderator on r/ethfinance:
"We are never going to make the blacklist public. Duh."
Other comment:
"There has been discussion with the old team about maybe letting the public vote on that somehow. It's a dumb conversation. That's why it's called a "blacklist". "
