istagram journey

hello i just bought 10 IG account non pva +3months ,semidedicated proxies ,massplanner and vps
for settings 250-350 follow and 50 100 like per day for all of them
i use browse to edit bio and add link i shorten link with goo.gl
i use ogads landing page hosted in ipage
for targeting i use geo location us while preparing a liste of big account in the same niche
result :
2 account banned
6 account stoped from followings till monday
2 account stilll running (i still dont add link to them)
for phone verification i use my phone im from morocco so i use moroccan number while using usa proxies is there a problem or its safe ?

so whats your advice to keep my accounts safe
i want to know whats the best tool to shorten my link bit.ly or goo.gl ?
its safe to use free win giveaway as username ?
whats the best settings should i use to stay safe ?
its better to send people to a blogger then landing page or its safe to send them directly to the landing page?
its safe to run follow /unfollow and liking at same time or should i run just follow /unfollow

Do not put your phone number for multipli accounts, instagram will flag it.
I don't think there's a difference between goo.gl and bit.ly, they're safe unless you are forwarding to Adult/ or any rejected content.
Start with 100-300 follows daily for 1-2 weeks, then you can follow 500-800
You can convert following and liking, but I didn't find that liking is effective so I put the energy on following

Goodluck and make sure to update us with your Journey
Also buy PVAs to be safer
