fromfiction:

It is perfectly acceptable to interact with the fandom of your kintype as long as you:

a) Don’t rub your kintype in the creator’s face, no matter how small or large their audience is.

b) Don’t attempt to tell other fans what they can and can’t do in fandom regarding your kintype or source. It does not belong to you.

Fandom belongs to everyone. Its okay to be fictionkin and still be in fandom, just don’t be a jerk or act with entitlement with regard to your kintype and source.

The same goes for soulbonds, fictives and fictional introjects as well.
