Systemli.org is a left-wing network and technics-collective that was founded in 2003. Our aim is to provide safe and trustworthy communication services.
Systemli offers a bunch of services as trade-free. However, some services like their e-mail service is only accessible if you have someone who invites you: “We have taken a conscious decision against an open registration system in order to prevent misuses of the service.” (https://www.systemli.org/en/service/mail/) Also their nextcloud service is only accessible if you have the e-mail address. Since these seem to be the only services that are kinda restricted, I would give 4/5 blocks, because all the other services seem to be perfectly trade-free.
