OCs deserve their own tag?

Posted under General

I plan to upload more images of this OC designed by me. (post #9654) I noticed that another OC has his own tag to make searching easier, so I wonder if this one can have his own tag, or does he need certain conditions to deserve his own tag?
maybe a certain minimum number of posts, that are relevant, follow certain guidelines, any parameters?
or maybe the original tag alone is enough.
I don't like to create unnecessary tags and then get into trouble.
