Growing Personal Accounts

My first post here was about 6 months ago when I started with FL to grow my personal account. It's a fitness oriented page so basically pictures of me lifting and other random stuff. At that time I was at 3300 followers..I'm currently at 18k. Has anyone else here grown their own page where they are the main draw to the page? If so how did you get to that next level? Should I try to find a sponsor so they will do some promoting for me? Any input would be great. Thanks.

We used to promote our main acc by creating bulk spam accs and comment with '@mainAcc'. That method is not working any more. Will get your acc(s) ban in no time.

This method still works fine with instagress. Just has to be older accounts. My 10 accounts all comment 100-120 daily. Also i mass follow, hence my 1k daily gain at least. Read more in my 50k in 50 days thread.
