I might be interested, however, I'm not sure if I would be a great fit.
On the one hand, I moderate a smaller community on this instance (!unbirth@lemmynsfw.com (vore-related community), and on my main account on another instance, I moderate five communities, though none have needed any moderator action to date. I also have experience as a former Discord mod for a community of 20K plus members.
On the other hand, I'm ace, and only lightly into BDSM, if you can even call my interests that. I think the memes here are enjoyable though, which is why I follow the community. However, while I'm sure action against accounts based on their involvement elsewhere on LemmyNSFW likely won't be common at all, if a situation arises where I do need to check an account's posting history, I likely won't be of much help considering I have a very large community blocklist.
