Hey, don't worry about it too much. People come and go as time passes. People will leave and it's often through no fault of your own.
I do completely understand the feeling of wanting to know why someone unfollowed you, but it is a big ask for people to always explain and justify why they unfollowed you. But don't worry, Newgrounds is a growing site and there will be plenty more followers in the future :)

Sometimes accounts are deleted or banned. Sometimes people follow users on a whim, without stopping to think if the person's content is something that truly interests them. I don't think it's fair to expect an explanation unless the person following you is someone you know on a personal level.
The real ones will always stay.

Yeah, I mean, even the galgos only follow the rabbit on the move and I've been as static as an ossuary so I can understand someone thinking "was I following her? Oh"
