Managing 1,000+ Instagram accounts

you wont need 1000 proxies for individual accounts most 4g proxies can house 30-40 accounts to safely conduct actions. dont use datacenter proxies tho, they have more tendency to be traced or linked to suspicious activity. as you wont be performing actions on all 1000 accounts at the same time, you can use anything around 20-30 4g proxies to perform actions. make sure rotate the ip before loging in to new accounts tho, that way they wont be linked to one IP address.

you dont necessarily need 1000 proxies. one proxy can work on 10-20 accounts, keep it organized in a spreadsheet and use that one proxy for 20 different accounts, that dont need to be online at the same time.

1000 accounts is crazy
try starting with 10 accounts before committing that kind of budget. Instagram's spam algorithm is really powerful
