The term "ghosting a convention" is when a person attends and hangs around, but has not paid the organizers to do so. It’s seen as a major faux pas in the furry fandom due to the amount of time, effort and money their fellow fans put forth in order to put on the events.
Those who support the festivities through their patronage, therefore, should be praised for putting their time and money forth to support their gathering of choice. For the relationship between convention and attendee is symbiotic.
Instead, certain events seem to have started to shun the precedent of sharing how many furs attended their celebrations. Like a tree falling in the forest, the con did occur; but if you look back years from now, there will be no hard evidence of how many gathered. In essence, it is the attendees who have been ghosted.
Which is why I am writing this piece today, concerning a worrisome trend that a handful of events seem to have taken - including some of the largest events in our fandom. Conventions, as of late, have been trying to push away from publicly putting forth their attendance counts.
Update 5/24: An updated tentative count was released by BLFC in the comments below.
Update 6/16: FWA has provided their counts with the video of closing ceremonies in comments below.
Update 6/16: AnthOhio, which took place in late May after the article was written, has as of today not released attendance numbers on any internet media platform. They did release charity numbers of $13,000 raised.
