Your biggest problem is that you're expecting things to happen inside of 24 hours. You're new, untested, unseen, a big unknown. Furthermore, 24 hours is hardly enough time to tell if someone has ghosted on you or not. Even if you made arrangements for daily posts, shit happens, and sometimes it happens a day late. Can't really speak for other sites, as I don't frequent them, and I have no idea how you conduct yourself. I will say making a public thread asking why everyone ghosts on you doesn't score a lot of points.

But is there more you could be doing? Oh yes. Let's talk about your interest check. [url=https://www.roleplayerguild.com/topics/175382-mxm-several-fandoms-search-my-hero-academia-the-legend-of-dragoon-tale/ooc#post-4800369]It's more bland than a milk and bread dinner.[/url] The first thing you open up with is a few vague bullet points, followed by some rather ordinary writing samples. While they might be honest of your writing capabilities, they are peppered with grammatical errors, and most will assume this is the very best you are capable of. After that we have a very, very, very, very, very, very, very narrow list of pairings that you are interested in. Then you're brazen enough to request better grammar after presenting those writing samples "For the love of all that is holy." There's very little to catch the eye, and the entire check feels like it was made in less than ten minutes. it doesn't really convey the image of a hard working, reliable poster who's going to stick with their RP till the end. 

Look at some other interest checks. Write clearly and concisely what you want. The minimum legal age is different all over the world. Just say you're thirty/twenty-seven/eighty-four. GMT timezone would have a lot more meaning if we know the hours you were available in "GMT." If you're going to insist on such few fandoms, maybe give other people the freedom to play a character they want to play outside of your ideal boy toy. It also helps to remove negative language, which can discourage people. Don't say you won't write with people with bad grammar, instead insist that you like to write at a "casual" or "advanced" level. Do all of this...

...and you'll still need more than 24 hours to get a hit. And even if people do bite, they could still ghost on you. Telling people not to ghost on you doesn't stop them from doing so. You could also join someone else's check. your extremely short time on the guild might make some cautious of you though.
