not sure if it's directed to me or not

anyways, i haven't answered, because i don't know the answer for most of these questions
So, if I use the same url on 5 accounts, it will be ok but if I use it on 6 accounts it will be instaban? Also, if you say the same url, does that mean that the same domain or the exact same URL (for ex. domain.com/xxx and domain.com/yyy)?
Can I 301 redirect the URL or does it have to be meta redirect? Or a lander?
i simply used free domains, i didn't bother with subdomains and redirects, so i cannot really elaborate on that
i used the same url per 5 accs and telling the truth, i'm not sure about the limits anymore, as somebody said he's using 10 accs with the same url, it can be 10, i just remember that i couldn't use the same url on too many accs, because all got banned and maybe i used the same url on only 5 accs to play a bit too safe
so it's either 5 or 10, test it
Does the IP has to be the same for sure? Because even if I were to use proxies I would get new proxies after every 30 days. I have a VPN where I can log in to the same region (London, Midwest US, Texas etc.) but the IP-s change every time. Will this result in instaban for Instagram (lol, I have a way with words)?
the ip question is a tricky one
i haven't managed too many accs since there's this pw reset fuckery, the ip rules were strict enough before and i can imagine it's gotten even more stricter
it would be the best, if you'd create the accs with the same ip what you're planning to use them with later on
personally i'd recommend using private proxies rather then VPNs, with VPN ips you can never be sure, they can be abused to hell
but before you'd do anything, you have to be sure that the proxies can be used on instagram at all, your best bet is asking the provider beforehand
with most providers, you can use the same ips throughout more than one payment cycle (for long months ideally, if there's no problem with the datacenters for instance) or replace them with new ones once per month
Can I use emulator on PC for this?
you can use an emulator named bluestacks or bots: the mega bot or followliker for instance
if you go with the private proxies & bluestacks route, there's a tool called proxycap what you can use to force bluestacks to run through your proxy
somebody hopefully can shed more lights on these questions
