You've posted a large amount of content that really doesn't fit the vibe of this instance. As another user mentioned this is literally LemmyNSFW not LemmySFW. You'd be better suited recreating the community that fits your specific interests on another instance.
On top of generally not being a great fit for the instance, the images you're posting are just not that interesting. We may as well be browsing a department store catalog or someone's instagram looking at advertisements. And I say this as someone with a deep appreciation for (mechanical)watches.
There have been meta discussions on this topic and there really isn’t a clear answer. It quickly devolves into “how do you define NSFW”. And there are good arguments for a broad variety of answers there.
Looking at OP’s particular kink as an example, one argument is that, even though you’re showing completely clothed people, you probably shouldn’t be showing pictures of sexy girls wearing watches on your work computer. It isn’t porn, but I think your coworkers would quickly see that you are getting a sexual kick out of it regardless. on the other hand, most people consider this a porn instance. There are a lot of things that aren’t safe for work that really don’t fit with what most people consider the purpose of this instance (porn).
As I recall, the instance doesn’t prohibit SFW content. It’s just that people here aren’t looking for SFW content and a lot of them are going to downvote SFW content because they don’t want to see it. The instance could try to tell people not to downvote these posts, but that’s not going to do much to change behavior. While some people do follow such guidelines, most aren’t going to follow upvote/downvote guidelines and are going to vote as they wish.
Yes, I agree that the definition of NSFW will vary wildly depending on the person or workplace in question. I don't have an issue with the fact that OP is posting "SFW" content personally as long as it's artistic, interesting, or has some sexual value for someone who is the target audience. However, at least two of those posts were literal Omega advertisements which isn't okay in my book.
I'm not arguing that SFW content should be banned or that it is not allowed on the instance, just what I've observed of user behavior in my time on the instance. If I don't like a specific user or community then I will block them if they are posting things that do not violate any community/instance guidelines. I wish more people would just do that themselves instead of pressing the 'fuck you I don't want to see this' button because that's all it means on Lemmy as long as something is posted to a community that it fits the guidelines for.
