I have 2 accts both less than 4 months old. One i didn't use at all for over 3 months and started using a month ago and is at 13k now. and another which I started about a month ago is at 7k but It was disabled once which caused a set back. But it works now and they are on track.
I gradually moved up my following my likes are definitely in the 1,000's but i did that right off the bat so I assume likes are fine.
But followers I started out following about 400-500 a day then gradually moved up about 50-100 more after a day or 2 over time. till I hit about 1500 a day or less which seems to be a sweet spot for me.
