Wh. Is this serious? Dude, I haven't rped with you, but I've also not heard a single negative thing about you! Like. At all! You shouldn't at all feel outed, and those tiny mistakes are way more forgivable than some of the other stuff that can be done. WCing? Happens to me all the time! And it's always embarrassing, but it happens to the best of us! That's nothing to feel ashamed of! Making roleplay/action related mistakes? Dude, when I'm rping, I'm in perpetual fear that I'm going to be gravely judged for me having my character wave, let alone speak to people. But I do it anyways! Because deep down I know I'm just being anxious and overthinking it. And when I do make emote related mistakes, of all sorts, it's easy to forgive!
You have absolutely no reason to be apologizing, as far as I've heard, seen or know of! Based off this post, it's not at all as bad as you think. A post apologizing to the entire server is something you make after doing something ban worthy or that makes the entire server gossip behind your back about how "this person is so toxic." FYI, no one I speak to has done or said anything like that about you! Honestly, you're perfectly fine. This is a Minecraft server. Don't think too much on it! And honestly, screw anyone who has the nerve to say you're some terrible, toxic person over a wrong chat or a mistake irp. Legit, screw them. It's absolutely pathetic to spend time insulting people for WC's and mistakes with rp to such a point that the person quits the server.
Happy Valentine's Day, b! I dunno the whole story, but seriously, from what I've heard, you have a far from negative rep. Don't let online harassment ruin your Valentine's Day! Have a great day! <3
