I don't even have an Instagram account. I sometimes comment on their posts on other websites. but not a lot and usually only when I notice someone that is unique or funny that isn't just about her beauty. like if an fbb reveals that she is old then I will compliment her. or I will compliment them when they perform extreme feats of strength or do other things that are rare. I will also comment more often on fbbs who are into the adult industry. since they tend to be more tolerant. I also try to ask them about their lifestyle sometimes. and sometimes they reply too so that is fun but it's rare and I even had a short chat with them.
One who is Haitian, we go back and forth on IG. She recently competed in a show and let me know how it was behind the scenes.
Talk with some crossfit athletes and like 3-4 fbb goddesses - mostly catching up and getting customs.
