I’m pretty it’s Beaver. I’m now banned (and I appear to be blocked by Beaver as well) and I’m pretty sure the only recent direct interaction I’ve had with the community was downvoting the recent articles about how vegan diets are okay for carnivorous pets.

Modlog does contain the info, it’s just not displayed on the website. You can get the full data from lemmy API

It is not federated with LW, but it is a nice, cozy, all-in-one space for vegans.\n\n***\n\nWe ask that the you have an understanding on what veganism is before engaging in this community.\n\nIf you think you have been banned erroneously, please get in contact with one of the other mods for appeals.\n\nModerator reports may not federate properly and may delay moderator action. Please DM an active mod if an abusive comment remains after reporting it.\n\n***\n\n## Welcome\n\nWelcome to c/vegan@lemmy.world. Broadly, this community is a place to discuss veganism. Discussion on [intersectional](https://en.wikipedia.org/wiki/Intersectionality) topics related to the animal rights movement are also encouraged.\n\n## What is Veganism?\n\n> 'Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals ...'\n\n— abridged definition from [The Vegan Society](https://www.vegansociety.com/go-vegan/definition-veganism)\n\n## Rules\n\n*The rules are subject to change, especially upon community feedback.*\n\n1. Discrimination is **not** tolerated. *This includes [speciesism](https://en.wikipedia.org/wiki/Speciesism)*.\n2. Topics not relating to veganism are subject to removal.\n3. Posts are to be as accessible as practicable:\n\t- pictures of text require alt-text;\n\t- paywalled articles must have an accessible non-paywalled link.\n4. Content warnings are required for triggering content.\n5. Bad-faith [carnist](https://en.wikipedia.org/wiki/Carnism) rhetoric & anti-veganism are not allowed, as this is not a space to debate the merits of veganism. Anyone is welcome here, however, and so good-faith efforts to ask questions about veganism may be given their own weekly stickied post in the future (see current stickied discussion).\n\t- before jumping into the community, we encourage you to read [examples of common fallacies here.](https://yourveganfallacyis.com/)\n\t- if you're asking questions about veganism, be mindful that the person on the other end is trying to be helpful by answering you and treat them with at least as much respect as they give you.\n6. Misinformation, particularly that which is dangerous or has malicious intent, is subject to removal.\n\n## Resources on Veganism\n\nA compilation of many vegan resources/sites in a Google spreadsheet:\n\n* [vegancheatsheet.org](https://vegancheatsheet.org/)\n\nHere are some documentaries that are recommended to watch if planning to or have recently become vegan:\n\n* [You Will Never Look at Your Life in the Same Way Again](https://www.youtube.com/watch?v=Z3u7hXpOm58)\n* [Dominion (2018)](https://www.youtube.com/watch?v=LQRAfJyEsko) (CW: gore, animal abuse)\n\n## Vegan Fediverse\n\nLemmy: [vegantheoryclub.org](https://vegantheoryclub.org/)\n\nMastodon: [veganism.social](https://veganism.social/)\n\n### Other Vegan Communities\n\n#### General Vegan Comms\n!vegan@lemmy.ml\n\n!vegan@hexbear.net\n\n!vegan@vegantheoryclub.org\n\n!vegan@slrpnk.net\n\n#### Circlejerk Comms\n!vegancirclejerk@lemmy.ml\n\n\n#### Vegan Food / Cooking\n!homecooks@vegantheoryclub.org \n\n!veganrecipes@sh.itjust.works\n\n!recipes@vegantheoryclub.org\n\n",

Thunder shows the mod for each modlog action.

The info is there. You can tell who it is by using the filters (e.g. logs filtered on me as the user that were modded by beaver: https://lemmy.world/modlog?page=1&modId=7121342&userId=36)

It’s a pain in the ass but it works.
