I'm selling my 29k Instagram account based on a celebrity / lifestyle niche. I haven't posted on it at all due to working on my other larger accounts, however I just checked its stats on Socialblade and it has been slowly growing organically without me posting.
If you can take care of the account and put any effort into it posting quality content, I have no doubts that it will grow much quicker than it is without anything being done to it.
NO RESERVE AUCTION - HIGHEST OFFER I RECEIVE TAKES IT!
