Obviously I’m not a moderator, but at the moment with the size of this community, I feel like that might be perhaps too limiting of a rule for now. Seems okay to me to try and if a moderator requests it to be removed then we follow that moving forward? Good question.
To add to this, this isn't Reddit, I'd imagine places would need to re-earn those bans again, from /m/manga's (/m/anga?) "staff/owner"
The reason why they were banned from reddit is that they were stuffed full with ads and the subreddit didn't want to be a party to people profiting off piracy. Scanlation is already sketchy enough.
