To cut this story short, if you really want to rank up and have a good reputation just do the opposite, stay active, learn more and expect nothing.
From my experience here's what I can share. Continue learning from this forum and just be yourself when engaging on topics. Don't be a trying hard just to converse on different topics that you really don't know just for the sake of merits. Think a timely issue that you can post on this forum where you share your opinion and also ask for the others. As time goes by, you won't notice that you're slowly ranking up.
