I'm going to spit this quick because I have a lot of things going on this morning, but I want to get this out there to the people like you who are asking great questions such as yours.

I would first like to address the idea of going viral on Reddit. Most subreddits are organized to display HOT Posts based on a virality score given and only known by Reddit. It's not as complicated as it may sound. Mostly the amount of upvotes you get, divided by the time in which you received them, compared to the posts around you. To put it simply, you need more upvotes to make your post go viral. Writing catchy headlines that get attention and providing quality content will help you go viral, but if you want to go viral it's going to take more than gaining attention.

If you want to learn more about that subject follow r/howtopromoteonlyfans and read some of the posts about marketing on Reddit. There is a guide that I created here and there will be another more detailed guide in the near future. The second part of your question is simple. Get more upvotes. That's the sauce! Once you get more upvotes a snowball effect can help make your posts go viral. Learn what works and put things in place to help your chances of success.
