I wouldn't worry about it too much, happens to the best of us. In some cases I have PMed the mod of the board after making an erroneous report that could waste a significant amount of mod's time (e.g. on plagiarism), or if I reported something completely ridiculous due to getting lost in my tabs - so that they didn't think I'm completely off my rocker . I don't think this is a major issue needing a new feature.
