Those who belong to the FON community are called “Foneros” Within the group of Foneros there are three basic levels of membership:
- Linuses: those who share their Wi-Fi and in return can get free Wi-Fi when using a FON Access Point.
- Aliens: those who do not share their own WiFi but pay a fee to use a Fonero Access Point.
- Bills: those who make money from their Wi-Fi. Linuses earn a percentage of the fees that Aliens pay to use FON.
There is some controversy about FON and its services that mainly arise around the legal issues associated with Internet Service Providers (ISPs). Some Internet users who are Linuses members may be breaking their ISP terms of agreement as their ISP may not allow its users to share their Wi-Fi connections or resell their bandwidth.
