Need to get a non FB group shared in multiple FB groups

I have a group, on a different site to Facebook.

I'm looking to get members to join the group.

I suggest to share the group on Facebook, need lots of shares in groups.
Niches, gaming groups, but also, computer, and general socializing groups.
Can also be shared on pages, or in direct messages. Please, bare in mind that FB may block if you share too much or get too many spam reports.

Its not a sales page, just trying to get people to join a group.

Looking for people with multiple FB accounts to share.
It's your recommendation how many times you should share per account.

Also, I am only looking to pay if the shares don't get deleted/blocked.

Please message me your cost, how many you can share?
Thanks
