You may think you're following the guidelines but still people won't like what you post and flag your post. It happens. As for why, I cannot tell you why other people do what they do, obviously, but I can guess a bit at some stuff:

1. You are doing self-promotion.

It's not directly against the guidelines, but it's generally not welcome by many. It's not the focus of the site and should be used sparingly. And, looking at your posting history, it's all you do. You're only submitting your own stuff. That is not really well liked around here.

2. It's about LLMs.

Again, it's not against the guidelines. But... it gets tiring. There's a lot of stuff on LLMs lately. And people are starting to get bored with everyone just posting about their particular LLM thing.

Not only that, but sincerely I didn't get what your thing does that is different to the other thousand LLM things posted. You seemed to focus in you explanation on a certain technical point but it doesn't really sound like an interesting thing at all. It's not clear whether your LLM thing is really different or relevant, or if it's just another one but with this particular technical detail.

3. Your text is not compelling.

This is related to the previous paragraph. I can't tell if you wrote what you submitted or if you generated it with an LLM. That would actually be against the guidelines and people would flag your submission.

But even if it isn't, well, it does kind of look like a block of copied and pasted text that an LLM would output. It's boring, also.

Finally, consider not submitting this. And I mean this "Why did I get flagged?" post here. These meta -posts are really not interesting and will get you flagged again easily. You get flagged? just accept it and continue.
