If some well-known member of the furry fandom isn't responding to all your messages, that doesn't necessarily mean they're selfish and arrogant. In the lion's share of cases, you're probably contributing to the exhaustion of their emotional bandwidth.
According to Dunbar's number...
By using the average human brain size and extrapolating from the results of primates, he proposed that humans can comfortably maintain 150 stable relationships. Dunbar explained it informally as "the number of people you would not feel embarrassed about joining uninvited for a drink if you happened to bump into them in a bar".
Here's some numbers (current as of this writing, will likely be changed significantly by the time you read this) from popular furries...
- Twitter followers: 62.7K
- YouTube subscribers: 235K
- Twitch followers: 3,870
- Twitter followers: 18.4K
- YouTube subscribers: 53K
Ace of Hearts Fox
- Twitter followers: 14.5K
- YouTube subscribers: 42K
- Twitter followers: 9.6K
- Twitch followers: 7,115
The numbers above are just their online followings. These numbers don't include their personal lives (boyfriends, girlfriends, nonbinary partners, family, household responsibilities, employment obligations, etc.) or any of their furry fandom projects that they're super passionate about and probably are the reason you wanted to talk to them in the first place.
When you attempt interact with a well-known furry, you're not interacting with a corporation that can delegate responses to a social media team. You're dealing with a single person.
If anyone can look at these numbers, contrast them with Dunbar's number, and still conclude, "I don't care, they're still selfish and arrogant because they won't respond to me," guess what: The selfish and arrogant one is you.
