Hello @amachado! Welcome to the Spotify Community!
Lithium is the very community forum web application you and I are using to talk to each other right now! If you scroll to the bottom of any Spotify Community page, you'll see a "powered by Lithium" logo in the lower right, just above the dark colored footer.
Lithium boards power a lot of different support communities, such as Skype, Best Buy, Sony Europe, Sephora, and Verizon, to name a few. It's actually my favorite online community tool for helping out users. But I digress.
It should be fine to leave it as approved since you created an account on Spotify's community, but you can cancel the approval if you so desire.
Let us know if you have any other questions!
