Every user accepts the Terms of Service with his registration. These are very clearly written: "On this instance, users who harass others will be removed. We also take a strong stance against e.g. racism, sexism, ableism, homo- and transphobia. Such expressions make the site unsafe for other users, and in practice limit their freedom of speech." That includes in this case a "PEGIDA USA" account as well as some more profiles by the same person. -> https://wiki.gnusocial.de/en:gnusocialde:tos
For anyone who doesn't agree, that's no problem for me. But then he/she should move to another node. I very happy to help on data migration. -> http://www.fediverse.org
