Founders are a special occasion, and very hard to get in some channels, and not everyone has the money to get the founder badge or have it every month which results in a lost of a lot of founders.

The following can be done:
Option 1: Give the person a Shiny Pink badge, like the 1st founder badge except with 2nd.
Option 2: Make it a Darker Purple badge, like the 1st founder badge except with a darker color than the Shiny Pink founder badge.
