Payment strategy

Currently we only charge per quota on some services and the process is manual.

Check options:

• Limit number of concurrent fairlogin sessions
• Quota on all offered services in LDAP per user
• Quota on all offered services in LDAP per group (more family and organization friendly!)
• Usage per day / month
• Sandstorm quota per user https://fair.sandcats.io/admin/hosting-management (requires both SAML and LDAP configured) see https://docs.sandstorm.io/en/latest/administering/hosting-provider/
• ~~~ Sandstorm credit card payment mechanism (removed now from blackrock, which is a more scalable backend for sandstorm) https://github.com/sandstorm-io/blackrock/commit/4045b833ebcbe3c2f88f44db8ac2a3f412c8f372 ~~~ deprecated
• Remove content if not paid after x months (e.g. in fairchat https://github.com/RocketChat/Rocket.Chat/issues/795#issuecomment-206897221 )
• FairCoin payment option
