Well Kailyn Lowry indirectly calls out her Teen Mom Castmates. She is talking about the strange trend among the Teen Mom cast (well mostly the 16 & pregnant cast who didn't make it to Teen Mom and wants to stay relevant).
They can make some money if their Sulia links get clicked on so they choose to write about the other cast members.
Kailyn posted "I wish the teen moms would stop writing Sulia links about the other girls on the show. If you're gona do Sulia write about another show!"
She does have a point that would be weird to have your cast mate writing something about you on their Sulia link.
Who is she calling out? Well the girls who do it the most are Ashley Salazar, Jenelle Evans, and Nikkole Paulun.
