I just put this together from the info on the website.
CleverLibre Social is an inclusive social instance for open discussion, learning, and community. All cultures welcome. Hate speech and harassment strictly forbidden.
It is not true that mastodon provides anti-abuse tools. See archives within 'playviscous.social' as mentioned within 'scholar.social'.
No mention of activitypub???
Once again:
mastodon ≠ fediverse...
