We are always working on improving the software (the last release introduced optional captcha support). Another measure we took today is switching the setting for new instances so they are not wide-open by default, and added a banner to remind admins that fully open instances need to be actively moderated, so this needs to be a decision that is careful the administrator,” Chaput added.droppedSince the arrival of Instagram Threads, another Twitter/X rival which also intends to federate by utilizing ActivityPub, Mastodon use happens to be trending down.
