I'm in the middle of starting this method myself. Everything can be easily found here on BHW except one thing. Good proxies for a good price.
For the past few weeks I have been testing several different proxies IPV4, IPV6, & Residential.
-Dedicated IPV4 & IPV6 lead to quick bans, just posting a few photos (no follows/unfollows)
-The better residential proxies work well for creating accounts, but it will get extremely expensive if you try to bot on them since you're paying for bandwidth instead of the per proxy.
Right now I'm in the process of getting a Raspberry PI built in order to create my own virgin 4g mobile proxies.
The child/fan account seems to work well & depending on the content quality/how many child accounts you have....
You can grow about 5 per day, per fan account.
