I just reached 112 myself.
I’m very much awaiting a time when users can block specific instances. I still don’t want to check the option to hide NSFW content, because I do want to see NSFW content that may show up on non-porn communities. Just not really interested in seeing so much porn in All.
You can check on your settings page, btw, in the Blocks tab - count quickly with Ctrl+F.
If you see them or anyone spamming on LemmyNSFW, please report them.
Our definition of spam may be different. I think of it on a personal level as “this guy / bot just cross-posted the same thing to five different communities within two minutes.” Others wouldn’t define that as spam.
