This change will only prevent UNfollowed tags.pub accounts from appearing in your local and home timelines, or showing up in public views of wandering.shop timelines. They should not have been there anyway so it is possible Proprietor is the first to notice the problem and we've stopped it before it started for anyone else. Detailed information on the service can be found at https://tags.pub/ Please report any anomalies, or reach out if you have concerns/questions.
