For one, it helps to link
the thread in question
This is fairly generic advice but I'd recommend avoiding titles like "Looking for fun RP" in favour of titles that are more descriptive of the thread's contents. It immediately tells us what you're looking for and makes your thread stand out at the same time. Try to include something about the kinks you're specifically looking for, or the prompts/pairings you're proposing.
As for the thread itself, the first thing you see when opening it is a long list of rules and OOC preferences, which I generally refer to as "important but boring stuff"; meanwhile, the fun stuff and the ideas you're looking for, are hidden beneath a spoiler, and the plots themselves are each under a separate spoiler too. I would do it exactly the other way around: begin with listing your ideas so that the reader has an idea of what you're looking for and what you offer, and put the boring OOC specifics at the bottom.
I do like how that "boring stuff" section is laid out, though: a list of two-word items can be hard to digest, whereas a large wall of text can be daunting to read. By writing full sentences after each bulletpoint, your rules are easy to both read and parse through. One thing that might improve it even more is by
highlighting certain words, e.g.
6. I will only play here on threads, and no where else. I do not have discord so instant chatting is out of the question.
That makes it even easier for someone to scroll through your rules and quickly check whether you're compatible in that regard.
On another typographic note, lots of italics can be exhausting to read. I'd recommend
only using them when you want to stress something.
