You mean in your rather specific fandom search thread? cause that's the first and foremost problem, people are checking your thread for the title and there are like a couple lines describing a situation of a fandom. Just a starter. there is no info about you, no alternatives, and "starters" are not how most people do roleplaying ads around here.
It's not people don't want to roleplay with you as a person its that your search thread looks picky and mal-constructed. Maybe that's the only thing you are willing to roleplay but in that case you have to be the one looking for a partner cause that is way too specific for people to come to you
