Facebook ghosting new accounts?

So I recently created a bunch of new FB accounts.

They were created manually with high quality images, backgrounds, clean residential IPs, phone verified with new SIMs etc.
Basically as good as it gets.

Most of them seem to have done well, slowly growing their friends and group counts. However, about 20% of them seem to be dead in the water from the get-go. None of them get more than 1-2 friends, and every time a new request is sent they get the "only add people you know" warning. The existing requests seem to have been ghosted.

Joining groups seems to have the same problem in the case of these accounts. I suspect FB is ghosting their group joining requests.

Does anyone have similar experiences? Any idea where it may have gone wrong?

It never happened to me and I work with fb accounts for a long time,I don't know what might be the problem,it is really weird.

Did you start using them asap you created them?

Are you using proxies? If so, make sure that the IP addresses are non-sequential.

Use only aged accounts for that dude,

Instead of adding friends, get people to add you. Join those ADDME INTERNATIONAL FRIENDS groups, post a message with a hot girls picture and say "I'm new here and I want to make 500 friends from here today, add me in 5 seconds!" You will probably receive 200+ requests..I did it with a male account and a weird gif and got 40+ requests from dudes in nigeria and india within 1 day, but I only needed my accounts populated with friends so I can join groups
