The accounts must be look very real with friends alot of activity of likes shares comments.
if your accounts will be look real facebook will never banned your accounts they will let you use it for more features on their website.
"Look real" seems a bit vague.
If you just add a full profile details like work, school, marriage status etc... it doesn't do shit.
Only activities matter. Even a 3 months old account with plenty of REAL USER activities is way better than a 10yo account but no activities. It's just an empty account that was created a long time ago. The activities I mean are interacting with people because FB is a platform created to connect people. Normal users will scroll their news feed x times a day, like x posts a day, comment on posts and talk to their friends.
Proxies? Anyone could easily detect if you're using proxies miles away. Your IP address will shows datacenter and it's super easy to detect an IP details. Residential proxy in my opinion is just a marketing technique, or it's just too expensive that hurts your ROI badly.
The only thing that works imho is buying a real active old fb accounts from real people in tier 3 countries. Use cookies to login the account. These accounts should be active not just old.
Old but inactive accounts barely work nowadays. Especially when theyre inactive for a while then you try doing some activities all of a sudden.
Proxies barely work now as well. Residential IP is one solution but still not guaranteed.
^ THIS! I've been saying this for months. Nobody listens. People keep wasting money on the "recipe" of 1 bot account - 1 proxy, at some point they'll open a thread with the title of "FB doesn't work" "FB is shit" "FB is dead".
I do not reply to this thread with the intention of promoting my sig. It's just my rant that so many guys who have little to no experiences with FB will give you advices that you feel trustworthy - just because they heard somebody said so. Meh. Do your own research. Start small, test the water, find a method then scale it up. Basically everything about IM works with that blueprint. I've been spamming FB for years, they do harden their algorithm, security and whatnot to prevent spam but I'm lucky enough to always find a workaround. Maybe I'll put up a guide later, it's just I'm so busy learning crypto trading these days.
