The sidebar says
This community is the place to discuss and ask questions about anime, anime news, and related topics
Emphasis mine. Episode discussions are created here constantly, so what’s the problem with linking a full legal episode of an anime?
The idea that if it was a trailer it would be fine is ridiculous
For context for others, OP posted a link to Slay the Gods Episode 1 which is a Chinese ONA series. In that post I removed, I replied before removal:
I understand that I didn’t explicitly have any kind of rule against posting links to publicly, legally available full episodes, so I will be clarifying that going forward soon when I get a chance (on mobile atm).
This community is really intended to be geared towards discussion/clips/news than sharing full-length episodes like that. Additionally, the episode was originally released almost two months ago, so it isn’t particularly timely (unless there is some wonky release stuff I am not aware of). However, I admit that this kind of thing was merely an intention on my behalf rather than something that all of us in the fediverse huddled together and decided collectively. So, I am open to feedback (such as this thread) on this kind of thing. In general, when I haven’t made rules about something, I tend to default back to what would have been allowed in the anime subreddit because they have had years of history to work through all the edge cases that can arise from rules.
I would be more open to posts of full episodes that are legally available if it was part of some kind of community effort. Say, for example, that OP wanted to organize a group to watch this series together and discuss it (like a rewatch in the subreddit). Then, there could be some kind of schedule and an episode post would get made each day/week/whatever and the discussion among members of this community could happen in that post.
I’m probably not going to watch anything hosted on YouTube (I blocked it completely a while back), but I don’t think it’s a big deal if someone links the first episode of something that’s legit freely available (i.e. not pirated) as long as they’re not being spammy about it.
Edit: to expand on that, we’re not exactly getting flooded with posts and that kind of restriction from reddit is more because of volume than anything, I think.
I’m not a mod of course, but I think posting full episode links would overshadow the bot discussion posts. We have those for a reason. At least for seasonal stuff.
