Hi I have reddit 150k karma account.
We already have a team for reddit
And I would really recommend you to form the group one time only as if you will get upvotes from the same account a lot of times you and your whole group will get banned.
This happened with us as well.
But now we are careful about it.
Remember: always getting traffic from reddit is not possible but when you will submit URL you will be benefitted a lot in terms of ranking as well.. faster indexing and link in comment on any subreddit is even counted by google very well. (only if your page get archived or a static post)
