I'm not sure if this is the right place or the right time to ask this, but could share/follow buttons inherit HTML link classes, that may be arbitrary or match a preset shipped with Bonfire (or its extensions)?
I'm just thinking about users asking not to follow them, or to share their posts, without asking, or if they don't know each other, etc. Ideally, arbitrary behavior could be asked, such as automatically denying a follow request, or showing a big pop-up to ask for confirmation.
