On the TFP articles index page, you can filter articles by their authors. To do that, you insert author:[username] (without the brackets) into the search field. The search is case insensitive, although whitespace characters matter here (so ryotamitarai is different from ryota mitarai, and ryota mitarai (with an extra space at the end) is different from ryota mitarai).
You're really cool and interesting and everybody thinks you're funny. Also posting tip; posting spam when one of your infractions is about to run out is lame and you probably have oily skin as well idk
