3-5 per day with days that you add 0 friends for example.
Monday 3 Tuesday 5 Wednesday 5 Thursday 4 Friday 0 Saturday 3 Sunday 0 that's 20 in a week, x this by 20 accounts and that's 400 a week.
Make sure you make accounts with 7/10 looking girls, late teens early 20's are the best and make sure you have 50+ pictures of the same person, 50+ pictures of memes, cool and funny stuff, 50+ of random mobile picture (random pictures that would be from a mobile phone).
Dripfeed pictures.
Turn follow on and start following 100 people a day this is far more targeted than any shitty add me groups or pages these are an absolute waste of time IMO the user are perverts who just add women to message an perv over them.
In my experience in 3-4 month you should hit the 5,000 mark and should gain more than that in followers.
