Mostly, I cut you if I looked at your name and I was like "I don't know who this person is," mostly because we've never interacted at all. It's not really about number of comments per se, but if I literally have no idea who you are cause we never talk/you never post (usually it's a combination of the two), then that's why I cut you.
If you feel that you were cut in error, please let me know! I might have made a mistake clicking all the little buttons and everything. Best of luck and thanks for all the fish! ♥
