I've been on reddit for 6 years, and I don't know that any of my posts have really gotten any kind of spotlight, but if I can have that once, I can only hope this is it.
I'm one of Unidan's personal friends. I run one of his YouTube channels with him (we are ad-less and don't make any money) and I've known him for years. I'm even the one who introduced him to Reddit. He has no idea that I'm stating this, and I don't really think that anything I can say can waver the great hive-mind, but I do want to bring some things to light that are very important to me:

I'm legitimately concerned for his well-being and safety. Even before today, he would calmly talk about the death threats and hate he would receive on a consistent basis. He had messages delivered to his actual home. I can only imagine what he is shouldering now. Please, please, please keep an eye out for him.
The man has definitely made a big mistake - one that in his own words was entirely unnecessary. He doesn't even want his old account back. He really just wants to continue contributing to the community like he has in the past. If you've ever been enlightened by his comments, laughed at one of his jokes, or got just a little more interested in biology or the natural world, please try to diffuse any malcontent or malicious gestures on your part or others. Help me by being a sentry in the comments. Rule #1 of this subreddit: respect Unidan's privacy. Some of you might not understand why he did this, but all I can tell you is that his passion and optimism for science and humor is authentic and that he is one of the most kindhearted and generous people I am lucky to call a friend. I hope you can see how much he has enriched the Reddit community and - despite his misdeeds - forgive him.
Thank you for any attention.
