I am on the right track now. I found out that Peepso shortcode was still in pages named the same as BP pages. So I deleted them all and made new ones for BP and they all are non peepso now.
For the Groups issue, it is still happening though, even after deleting permanently the Groups page (in case attache din anyway with Peepso).
All users are still marked as spammers. If i have to re enter them manually I will.
I will have to try the register process now as it did not work before.
