Got a reply from the person behind @mastodonanalysis
"Thank you for your note and I apologize for causing harm. As part of a class project I was trying to explore the topological structure of mastodon and identify structures for creating safe spaces in other online communities. I chose this name to alert admins to my intentions. I thought that the only harm caused by downloading data could be server overload which is prevented by API limits. The last thing I wanted to do is cause harm to your community and I have stopped downloading data."
@href If you have a minute, may I ask you if you could you link to the related story?
@ffeth Not much, but look here: https://tenforward.social/@guinan/98989563639745953
Mosts admins banned/blocked the bot. I contacted the owner to learn more (see https://soc.ialis.me/@admin/98991669668172738 )
@href what have he downloaded ?
@marsxyz not sure, he didn't reply this specific question / privacy. However he just scrapped the account endpoint so name bio following followers. public stuff.
@marsxyz IMO it's a non issue. That's why I decided yesterday to first contact the bot owner before taking any action.
The bot owner stopped his research for now & will try contacting the community.
(IMO a topology/research of the fediverse network would be an AWESOME research.)
@marsxyz lot of admins saw the bot as agressive and evil.
@href if he access the same URI style every X times, just make a fail2ban jail for that :D
@dashie That would prevent him. He already stopped.
That would not prevent any kind of real, privacy sucking, bot. Doing a stealth one is a breeze on the fediverse.
