Well, it'd be easier if you got a shoutout from those big accounts otherwise it'd be slow to grow by yourself.
If you have an OG account that relates to your posts it'd be faster, also tag perfectsayings. He shouted me out for free from a post.
Mainly stay really active when you're first starting post a pic every hour to an hour and 30 minutes. Start with getting a shoutout for like 1k one of the Ryans will grow you 1k for like $20. Start with that and you'll eventually grow a lil. I'd be willing to shoutout you out a little for nothing just PM me your @.
Me and my gf run a frog text post account(LOL) but ya she runs a 240k stat and the 9k we made just 2 days ago but I'd say ask around for shout outs and shit also be extremely active
