Hello and welcome (welcum, perhaps?)
@hucow. I will attempt to answer your questions to the best of my ability. First off, my thread is probably among the more disorganized (or perhaps not, this is just my own self-criticism) on the site, and the fact that I have multiple doesn't always make things as straightforward as I'd like. That said, I believe it comes down to several factors. One possible factor is the ratio of males to females, both for actual players as well as the characters they are willing to play. It may be that female characters are more popular than males, although the last time I personally read someone's take on this was a while ago, and that could have changed in the interim.
Another factor is what's in the thread itself. Just as an example, an expressed interest in, say, creampies as a kink could possibly attract more partners than interest in your high-elven, quarter-goblin princess having sex with an anthropomorphic unicorn who can also shapeshift into a dragon. The more wide-ranging and popular your kinks and interests are, the higher chances you have of success.
Yet another is timing, both in terms of the time of day you bump your thread, as well as the time of year it is. Some, perhaps a great deal of users on Blue Moon are in college, and still others have children who are between the ages of 5 and 18. Whichever the case, those users have a different schedule now that the academic year is starting in many parts of the Western world, and their activity level on Blue Moon will change accordingly. Circling back to the time of day you bump your thread, a great deal of users are from English-speaking countries, mostly the US, Canada, the UK and Australia, with a healthily diverse group of other folks whose second or even third language is English. Regardless, if you wish to cast the widest possible net, experiment with various bumping times (keeping in mind the bumping policy, of course) when most Americans are awake. If that conflicts with your schedule, I apologize, but I assumed you are, in fact, American. Please correct me and accept my apologies if I am wrong.
I cannot speak to the average amount of requests a given person gets on the site, but I find that I get one or two each time I bump, or at least, I haven't gotten any if I didn't bump. Regardless, I consider a request successful when the roleplay has truly begun. By that I mean that the partner and I have each made at least a few posts and the story and the writing is flowing freely, so to speak. In fact, I easily can drop people and have even deleted threads because the flow was broken before the story truly took off. I may try to be patient myself, but I have little time for people who say they'll do one thing and then not do it. But I didn't come here to vent to you or anyone else.
In conclusion, there are several things that dictate success. Some, as I said before, you can control, others, not so much. Experiment and tweak what you can control, and learn to accept what you can't, and you'll have a wonderful time here. I hope you have a wonderful rest of your day, week, month and year. Stay safe and take care!!
