Nope, I break all the rules of self promotion and have never faced any severe consequences from it. There are only 2 small subreddits that have taken my posts down and told me I have to balance what I post, but if I wait like 2 months, I'm able to post there again. But I will recommend that you create your account a month ahead of time and participate, share content that isn't yours just to boost your post and comment karmas. I really don't think people care about your 'name,' at least in the 20 subreddits I use. Perhaps it's different on whatever niche you're in.
Here are my best tips on how to succeed in Reddit:
1. You have to really need to understand the voting system, how long a video stays number one given how many upvotes it got and how fast it got up votes. This also depends on how big the subreddit is. From my experience this takes weeks or months to get a good feel for this, but it's REALLY REALLY important. I'll often time posts when the number one or two trending has passed its peak. Because the reality is, usually only the top video in the subreddit gets all the views because they appear in people's homepage.
2. Creating good titles is very important. Don't always use the same title you used on Youtube. Think of the needs of the people in the subreddit. Again this takes time, and perhaps a lot of trial and error to get a good grasp on
3. Respond to every or most comment you receive as this increases the comment count. Growing big on Reddit is all about popularity. If people see a video or post with lots of upvotes and high comment count, they are more likely to upvote the video. This is just basic human psychology. I can upload a video in a subreddit that doesn't make number one, and it get's a 56% upvote with only 6 points. But if I reupload the exact video at a later time with better timing, it can get an 86% upvote with over 1000 points and get thousands and thousands of views. Reddit is all about snowballing.
4. Your content has to be good and relevant to the subreddit. Reality is, if your competitors are posting better content than yours, than they'll have a better chance to succeed. So if you have a competitor that you know generates high upvotes, don't post yours when he/she has recently posted. If they have a posting schedule, take note of it and avoid those times.
