Is there any Facebook bot that can post in multiple groups with multiple accounts ?

Hey guys
recently i am looking for a tool which can auto post to multiple Facebook groups.
because i wanna gain some traffic from it.
I tried Hootsuite and i joined 2000+ groups (i used 20 accounts),but it seems most of my message get blocked and few accounts posted successfully.
So im still looking for a powerful tool.
Any idea?
