I meant as in post content and/or moderate. Viewing is not always enough. Plus, there isn't that much content on Lemmy to view anyway.
And people can publically see on my profile which communities I'm subscribwd to, so that doesn't go well if I subscribe my "normal main" to c/UpvotedBecauseOfBoobs. Basically, I have to switch accounts to comment, which is fine, I do it all the time on Reddit, but the app doesnct bring you back to the post you originally viewed, like Reddit does. So, I have to remember the community name, search it in my communities and then search for the post, which, sorry to say, is just a whole lot of time wasted.
Not to mention I also join "normal" subs from my "not so normal" alts to get the feeds there as well, so I can just get the post, view it and switch accounts to comment. I can't do that here. Why? Cuz most other instances will choose to defederate from NSFW instances š... which I can't see any reason for amyway, it's not like they host the NSFW content, they just provied the feeds, that's it.
And let's say I decide to open a new account on an instance that doesn't block NSFW instances. That instance can one day decide to block NSFW instances in their feeds. So, here we go again, I have to look for an instance that doesn't block NSFW content (which is not clear when you join an instance, you have to join it, then realize that it has a whole NSFW block list) and start all over again... I mean, it's just so time consuming.
I have a total of 3 accounts on Reddit and I have managed to separate stuff with those 3 perfectly so far. Here, 10 accounts might not be enough if every non-NSFW instance decided to defederalize from NSFW instances.
