OK, i figured out this one. This is actually an issue of the bridge:

If you are in a channel where other users are which start with @slack_ but isn't part of your puppeted slack, such as #matrix:matrix.org the regex in slack-registration.yaml will give a alse positive.

To fix this, change the regex from like regex: '@slack_.*' to regex: '@slack_.*:sorunome.de' where sorunome.de is your homeserver thing
